Title: The Radio Lobe/ICM Interaction in the Unusual Radio Galaxy 3C 310

PI Name: Steve Murray

We propose a 60 ks observation of the hot gas around the unusual double-lobed radio galaxy 3C 310 to constrain the dynamics of the gas interaction with the radio bubbles. The radio emission from the lobes of 3C 310 show a variety of shells and filaments embedded within a larger scale diffuse emission. The southern lobe had a bright ring in the center, similar to the one seen in Her A, that may be the result of a complex interaction between the buoyant bubble and the ICM. Two merging elliptical galaxies lie at the center of the cluster gas. This observation will permit us to determine what effect that dynamic cluster gas, stirred up from the merger, had on the evolution of the radio bubble.

Title: Monitoring of the X-ray Jet and LMXB population of Centaurus A

PI Name: Steve Murray

We propose 2 5 ks monitoring observations of the jet and LMXB population of the nearby radio galaxy Centaurus A. These monitoring observations will be used to search for any long term variations in the X-ray brightnesses of the jet knots. Any dramatic variability would, if detected, give us important constraints on the spatial scales involved in the shock acceleration of ultra-relativistic particles. Such scales are well below the spatial resolution of Chandra and can only be probed via their temporal variability. Additionally, we will continue monitoring the brightest 100 LMXBs, and the 2 ULXs in particular, to build up a time history of the population over more than a decade.

Title: A Deep Chandra HETG View of Outflowing Warm Absorbers and Relativistically Blurred Emission in ESO 323-G077

PI Name: Claude Canizares

We propose a 300-ks Chandra HETG observation of ESO 323-G077, a remarkable Seyfert galaxy that shows evidence of two highly ionized warm absorbers and a relativistically broadened Fe Ka emission line (Jimenez-Bailon et al. 2008). We will use the high energy resolution of the HETG to provide the first strong constraints on the nature of the absorbers, and test the hypothesis that they form part of a two-phase outflow from the AGN. We will also this detailed parametrization of the underlying X-ray continuum and circumnuclear absorption to determine if the Fe Ka line is relativistically blurred. Finally, we will use the zero-order HETG image to explore the relationship between any spatially extended X-ray emission and the known [OIII] emission that forms the narrow-line region.

Title: A Survey of X-ray Variability in Bright Broad Absorption Line Quasars Over Multi-Year Timescales

PI Name: Gordon Garmire

We propose to observe 10 optically bright BALQSOs with short (5-10 ks) Chandra observations aimed at searching for any strong X-ray variability. The targets include the optically brightest BALQSOs in the sky that already have sensitive archival X-ray observations with Chandra, XMM-Newton, or earlier missions. Our goal with these short observations is to perform a basic exploratory survey for strong X-ray variability in a sample of respectable size. We will be exploring important rest-frame timescales of up to about 5-8 years for the first time in an effective manner.

Title: Studying the Optical and X-ray Emission Regions of Quasar PG1115+080 by Monitoring Microlensing Events

PI Name: Gordon Garmire

We propose to apply the microlensing method to constrain the spatial structure of the optical and X-ray continuum emission regions of the quasar PG 1115+080 by comparing the flux ratios of the images in the X-ray and optical over several epochs. The differential changes in the flux ratios with wavelength will then constraint the relative sizes of the optical and X-ray emission regions.

Title: Investigating the Complexity of NGC 2992 with HETG

PI Name: Claude Canizares

NGC 2992 is a nearby (z = 0.00771) Seyfert galaxy with a variable 1.5-2 classification. Over the past 30 years, the 2-10 keV continuum flux has varied by a factor of ~20. This was accompanied by complex variability in the multi-component Fe K line emission, which may indicate violent flaring activity in the innermost regions of the accretion disk. By observing NGC 2992 with the HETG, we will obtain the best constraint to date on the FWHM of the narrow, distant-matter Fe K line emission, along with precision measurement of its centroid energy, thereby enabling more accurate modeling of the variable broad component. We will also test models of the soft excess through measurement of narrow absorption lines attributable to a warm absorber and narrow emission lines arising from photoexcitation.

Title: The chemical composition of AGN outflows

PI Name: Jelle Kaastra

We propose a simultaneous Chandra LETGS - HST/COS observation of the bright Seyfert 1 galaxy Mrk 509, within half a year from an approved large XMM-Newton monitoring campaign. Combining 180 ks LETGS time and 10 orbits of COS time with the XMM-Newton RGS spectrum, we will obtain accurate abundances of C, N, O, Ne, Si, S, and Fe over a broad range of ionisation parameter. This allows us to determine directly the contributions from various supernova types and intermediate mass stars to the chemical enrichment processes in galaxy cores. It also will reveal directly the chemical composition of the outflow that enriches the surrounding diffuse medium. Our team has succesfully executed a similar abundances campaign on Mrk 279.

Title: UGC408: two big bangs from a modest size black hole?

PI Name: Christine Jones

UGC408 is a prime example of an interaction between an FR I radio-source and the X-ray ISM. The existing Chandra observation reveals a large (20 kpc) cavity in the X-ray gas approximately centered on the galaxy nucleus as well as X-ray emission from the nucleus and a small 5'' jet. GMRT radio observations show emission from very extended low frequency radio plasma that overfills the X-ray cavity. A comparison of the X-ray and radio images suggests that two AGN outbursts have occured. We propose a deep 95 ksec observation to 1) investigate the interaction of the radio lobes and jets with the X-ray emitting gas, 2) determine the age and total energy for each AGN outburst and 3) better characterize the structure, spectrum and extent of the X-ray jet.

Title: A Chandra Observation of the Jet-Cloud Interaction in the Centaurus A Northern Middle Radio Lobe

PI Name: Ralph Kraft

We propose a 70 ks Chandra/ACIS-S observation of the brightest knot of the X-ray filament associated with the Centaurus A Northern Middle Radio Lobe (NML). Our XMM-Newton observation of this feature determined that the emission was thermal and most likely the result of a jet interaction with cold, dense gas. Our observation will study shocks and other surface brightness features in the filament to better constrain the velocities and overall energetics of the interaction. In particular, we will assess the relative importance of shock-heating versus ablation in the interaction. Cen A is the closest powerful radio galaxy, and we can study features of the jet-cloud interaction that would be unobservable in any other object.

Title: Resolving the NLR/ENLR Shocks in the Radio Galaxy Coma A

PI Name: Daniel Evans

We propose a 25-ks Chandra/ACIS-S observation of the extended narrow-line region (ENLR) in the radio galaxy Coma A - the first X-ray imaging observations of this powerful radio source. We will use Chandra's superb spatial resolution to examine the relationship between the X-ray-emitting shock-heated gas, radio jet, and optical line-emission. We will determine the role of shocks in imparting energy into the ambient IGM and assess the part that ionizing nuclear radiation plays in governing the ENLR. Coma A has key implications for AGN feedback: it is a direct analog of powerful, high-redshift, radio galaxies that are known to have large quantities of galaxy-scale cold gas. Our Chandra observation will give us a unique opportunity to spatially resolve the jet-gas feedback process in action.

Title: Coordinated Multiwavelength Observations of New TeV Blazars Detected by VERITAS

PI Name: Markus Boettcher

We propose a 40 ksec ACIS-S ToO observation on a new TeV gamma-ray blazar detected in a very-high-energy (VHE) gamma-ray flaring state by VERITAS. The proposed Chandra observations will be coordinated with ground-based radio, infrared, and optical observations as well as VERITAS VHE gamma-ray observations. Together with the guaranteed MeV - GeV gamma-ray coverage by Fermi, this will provide as complete coverage of the entire broadband spectral energy distribution as currently feasible. Simultaneous coverage of the entire broadband spectrum is crucial to put stringent constraints on gamma-ray emission models of blazars as well as the extragalactic background light.

Title: The nature of X-ray jets in powerful core-dominated quasars

PI Name: Martin Hardcastle

There is considerable debate about the nature of the X-ray emission from the jets of core-dominated radio-loud quasars (CDQ). A popular model proposes that it is due to inverse-Compton scattering of microwave background photons; however, there are some serious observational and theoretical arguments against this model. Determining the X-ray emission mechanism has significant implications. The inverse-Compton model implies a large bulk Lorentz factor that persists to kpc scales: constraints on jet speeds affect our understanding of jet formation, evolution and feedback. Here we propose to carry out a straightforward test of a fundamental prediction of the inverse-Compton model by constraining the X-ray spectra of jets in a small sample of CDQ and comparing them with radio measurements.

Title: Rapid Follow-Up Observations of Tidal Disruption Events Discovered by Pan-STARRS1

PI Name: Suvi Gezari

We propose for rapid follow-up Chandra TOO ACIS-S observations and HST/COS NUV imaging and FUV low-resolution spectroscopy of 5 flares from the tidal disruption of stars by supermassive black holes discovered in the Pan-STARRS1 Medium Deep Survey. With TOO observations obtained within a month of the peak of the flare, and 5 months later, we aim to 1) constrain the flare's broadband SED and bolometric luminosity, 2) follow the decay of the flare and look for spectral evolution, and 3) place strong limits on the presence of a persistent AGN nucleus. Tidal disruption events provide a cosmic laboratory to study the physics of accretion onto black holes, and are a unique probe of the mass of black holes in the nuclei of distant galaxies.

Title: X-ray Signatures of Accretion in AGNs with Intermediate-mass Black Holes

PI Name: Luis Ho

Supermassive (10^6-10^9 solar mass) black holes (BHs) are closely linked with the evolution of early-type galaxies. Our group has discovered a new class of AGNs with intermediate-mass (10^4-10^6 solar mass) BHs in late-type galaxies. These objects offer important clues to the nature of the seeds of quasars, and their mergers may produce significant gravity waves. We have started to systematically study their multiwavelength properties. A pilot Chandra program revealed that they are unusually X-ray bright, possibly because their low BH masses and high accretion rates sustain a slim accretion disk. We propose to extend and confirm our preliminary results by performing a comprehensive survey of the X-ray properties of a larger sample of this new class of AGNs.

Title: Hunting for Intrinsically X-ray Weak Quasars: The Case of PHL 1811 Analogs

PI Name: William Brandt

A central dogma of X-ray astronomy is that luminous X-ray emission is a universal property of efficiently accreting supermassive black holes. One interesting challenge to this idea has come from the quasar PHL 1811 which appears to be intrinsically X-ray weak and also has distinctive emission-line properties. We propose to observe a sample of eight SDSS quasars, selected to have similar UV emission-line properties to that of PHL 1811, to test if they are also X-ray weak. Our analyses of the currently available X-ray data appear to support this hypothesis but do not provide a proper test. Our results will have implications for the nature of accretion-disk coronae, emission-line formation, and AGN selection.

Title: The nature of active nuclei in radio galaxies: observations of the 2Jy sample

PI Name: Martin Hardcastle

We propose Chandra observations that will provide a complete, unbiased sample of radio galaxies drawn from the 2Jy sample, which already has excellent radio, optical and mid-infrared data. Our primary goal is X-ray spectra of the active nuclei: we will detect or put strong upper limits on the heavily obscured continuum emission that indicates a radiatively efficient AGN, and combine this with the uniquely good data at other wavelengths to establish a definitive picture of the ways in which black-hole activity manifests itself in these objects. We will test models in which the optical line emission class indicates powerful, radiatively inefficient AGN. We will also constrain the hot-gas environments of our targets and test models that relate accretion mode and environment in radio AGN.

Title: Weak-line Quasars: Always X-ray Weak?

PI Name: Karen Leighly

We propose to explore the link between the shape of the spectral energy distribution and UV emission lines in quasars. Detailed study of the bright quasar PHL 1811 shows that the unusual emission line properties including low high-ionization lines, absent forbidden and semiforbidden lines and strong SiII and FeII are a consequence of its persistently X-ray weak SED. Are all objects with weak lines also X-ray weak? To test this hypothesis, we use an automated fitting program to construct a sample of SDSS quasars with spectra similar to that of PHL 1811, and select 10 objects with CIV equivalent widths less than 10 angstroms (a factor of 3 lower than typical) yet bright enough for detection even if a factor of 11 weaker in X-rays than typical quasars.

Title: Exploring the X-ray - TeV connection in BL Lacs on short timescales

PI Name: Sarah Kaufmann

We propose to perform one ToO for a full night (30 ks) of simultaneous observation with Chandra and H.E.S.S., on a flaring TeV blazar with flux high enough to constrain both spectra on hour timescales or less. Our goal is to investigate with unprecedented detail the intra-night and sub-hour variability in TeV blazars, as strikingly revealed by recent H.E.S.S. observations on PKS 2155-304 (few minutes flux doubling timescales). The aim is to shed light on the origin of the gamma-ray emission and on the relation between X-ray and gamma-ray emissions.

Title: The X-ray - TeV Connection in M87

PI Name: Daniel Harris

With observational data from VERITAS, HESS, and MAGIC, it appears that there are TeV 'high states' for M87 which can last a few weeks and provide many nightly detections at a level significantly higher than the 'quiet state'. Because we model the TeV emission as IC scattering by the same electrons responsible for X-ray synchrotron emission, we expect that TeV variability will be mirrored in the UV and X-rays. To determine the location of TeV emission and to obtain quasi simultaneous photometry to refine sync/IC calculations, we request a Chandra TOO program on M87 to be triggered by the TeV 'high state' condition. We request a maximum of 90 ks, divided into 5ks observations so as to construct a light curve for comparison with those obtained by the Cherenkov observatories.

Title: The Cavities and Jet-cloud Interaction of PKS B2152-699

PI Name: Andrew Young

We propose a deep, 125 ksec Chandra ACIS observation of the powerful radio galaxy PKS B2152-699. An existing short ~14 ksec Chandra observation has shown i) cavities being inflated in the inter-stellar medium (ISM) by the radio lobes, and ii) X-ray emission from a jet-cloud interaction region about 10" northeast of the nucleus where the jet is running into a cloud of dense gas and being deflected. As a result, PKS B2152-699 is the best source for estimating both the time-averaged jet power and instantaneous jet power in a single system. In addition, we propose optical integral field unit spectroscopy of the jet-cloud interaction region to complement the X-ray data to understand how this gas is being ionized.

Title: Deeply embedded AGNs in infrared ultraluminous starbursts

PI Name: Guido Risaliti

We propose to observe a small group of three Ultraluminous Infrared Galaxies optically classified as starburst or LINER, which according to our analysis based on Spitzer 5-8 micron spectra hide obscured active nuclei. These AGNs account for >50% of the total source luminosity, which puts them among the few known QSO2s al low redshift (z<0.25). The Chandra observations will test our prediction, possibly providing a direct evidence of these hidden nuclei. While it is well assessed that most of the luminosity of local ULIRGs is due to starbursts, our observations would further increase the fraction of these objects known to host a heavily obscured AGN.

Title: The Size of Quasar Non-Thermal/X-ray Emission Regions

PI Name: Christopher Kochanek

We will use microlensing, where the stars in a lens galaxy magnify the accretion disk of a gravitationally lensed quasar, to measure the sizes of the X-ray emission regions of 7 gravitationally lensed quasars with well-sampled optical light curves and accretion disk size measurements. We will use these to determine the scaling of the non-thermal emission regions with black hole mass. For two ``active'' systems, RXJ1131-1231 and Q2237+0305, we will use longer observations in order to measure the X-ray energy dependence of the size. We have HST time to monitor the 6 with UV flux to probe thermal emission from near the inner edge of the disk. These observations can only be done with Chandra because future X-ray observatories will lack the necessary angular resolution.

Title: Is there an AGN in the Blue Compact Dwarf Galaxy Mrk 996?

PI Name: Antonis Georgakakis

We propose Chandra/ACIS-S observations to explore suggestions that at least some Blue Compact Dwarf Galaxies (BCDs) host AGN. Mrk 996 is an excellent test-case for this scenario. It has a unique set of observations, which allude to the presence of an AGN, yet many of its properties are typical of the overall BCD population. The detection of an AGN in Mrk 996 would demonstrate that black hole growth is taking place in low mass/metallicity BCDs, which are thought to be the local analogues of the first galaxies that formed in the early Universe out of near-primordial gas. This would offer a solution to the origin of seed black holes postulated by cosmological simulations in the early Universe to build the supermassive black holes at the centres of large spheroids.

Title: The environmental and epoch dependence of radio-loud AGN feedback

PI Name: Judith Croston

Feedback from radio-loud AGN outbursts is now thought to be an important ingredient in galaxy formation models, potentially solving the `cooling flow' problem in cluster centres and helping to resolve long-standing problems in reconciling CDM models with observed properties of groups and clusters. Now that the role of radio-loud AGN feedback is established, the next step is to understand the relationship between radio-loud AGN energy input, environment and epoch, which appears complex and is currently poorly understood. This Chandra Large Project aims to address this question by characterizing the environments of a unique sample of radio galaxies spanning three orders of magnitude in radio luminosity at a single, cosmologically interesting redshift.

Title: NGC1266: Local Candidate for AGN Feedback

PI Name: Leo Blitz

We propose to use Chandra to probe the unique early-type galaxy NGC 1266, in which we may be directly observing the truncation of star formation via feedback, taking advantage of Chandra's superior spatial and spectral resolution. We will combine a 30ks Chandra ACIS-S observation with our existing multi-wavelength suite of data and with detailed theoretical modeling. The X-ray data are an integral component in the analysis of this object and will provide information unavailable in other wavebands, including whether the source of NGC 1266's large-scale ouflow is an AGN or a starburst and how the outflow is affecting the galaxy's ISM. This information will thus enable a new and more nuanced understanding of the role of feedback in truncating star formation in early-type galaxies.

Title: Imaging Strong Shocks in the Compact Steep Spectrum Radio Galaxy B3 1445+410

PI Name: Christopher O'Dea

Strong shocks are expected to be important during the AGN dominated epochs of galaxy formation and evolution. However these shocks have not yet been detected at high redshifts. Here we propose to observe a radio galaxy which should produce strong shocks, but at a redshift where we can detect and resolve the hot gas easily. This is only possible because we will observe a relatively nearby young radio galaxy. Using XMM we found evidence for a strong shock (Mach 13) around the Compact Steep Spectrum (CSS) Radio Galaxy 3C303.1. We propose to obtain Chandra imaging of the CSS source B3 1445+410 which is larger and lower redshift than 3C303.1. These observations will provide the key next step in the study of radio source propagation and feedback to the host galaxy.

Title: X-ray Obscured Broad-line AGN

PI Name: Jennifer Donley

While most Type 1 AGN show little or no X-ray obscuration, ~10% are heavily obscured in the X-ray with column densities typical of Type 2 objects. We propose to observe with Chandra a sample of 6 such AGN, which appear to defy the most fundamental assumptions of the unified model. Chandra observations are critical to place tighter constraints on the level of obscuration and to check whether it is variable. When combined with Spitzer and optical polarimetric data, the Chandra data will allow us to test for the first time the many potential explanations for the strange properties of these AGN. Our study will provide unique insights into the structures and processes active in and around the central engines of AGN, and will provide a demanding test of the unified model.

Title: Variability and particle acceleration in the jet of Pictor A

PI Name: Martin Hardcastle

Pictor A is one of the closest FRII radio galaxies and one of a very few to show a continuous, bright, 100-kpc-scale X-ray jet. It thus represents a crucial link between low-power FRIIs with weak discrete jet knots described by an X-ray synchrotron model and powerful core-dominated quasars whose X-ray jets are often modeled as beamed inverse-Compton. It is vital to understand the nature of the jet emission in this key object. We propose a long observation that will give us a substantial improvement in spectroscopy and imaging of the bright inner jet, and will in addition allow us to confirm the first, but so far only marginally significant detection, of variability in an FRII X-ray jet. Many additional projects can be carried out with these observations.

Title: Strong radio AGN in the center of galaxy groups

PI Name: Ming Sun

Outbursts of radio AGN have significant impact on structure formation and evolution. Radio feedback can quench cooling flows and modify cluster scaling relations. It has been suggested that a cool core is always required for strong radio AGN of BCGs. However, groups and clusters with strong central radio AGN previously observed by Chandra are almost all X-ray selected. We propose to observe a complete sample of groups with strong central radio AGN, optically selected from SDSS. Without X-ray selection criteria, this sample will test the ubiquitous connection of cool cores and strong radio AGN of BCGs. The selected radio AGN are expected to leave significant imprints on the surrounding ICM (e.g., cavities, shocks, reduced gas fraction and elevated entropy), which will also be examined.

Title: A Joint Chandra, Fermi, MAGIC, and VERITAS Broadband Study of One High-Energy Blazar in A Major Outburst

PI Name: Alexander Konopelko

The main objective of the proposed work is to perform a single very intensive observational campaign at radio, X-ray, GeV, and TeV energies on one of the well-established northern sky TeV blazars, i.e., Mkn 501, 1ES 1959+650, H1426+428, or 1ES 2344+514 with Chandra, Fermi, MAGIC, and VERITAS.During planned multi-wavelength campaign the SED of one blazar will be covered by simultaneous observations with VLBI, Chandra, Fermi, MAGIC, and VERITAS all the way from radio through TeV γ rays. Our scientiﬁc goal is to derive ma jor physical parameters of the AGN jet by reproducing the complete SED, using both leptonic and hadronic models, which can infer the bulk Lorentz factor and the total power of the jet.

We identify a likely variability timescale of 1 week, and we propose to monitor the source for 2 weeks and explore all shorter timescales by making use of Chandra and XMM-Newton unique capabilities.

Title: AGN ignition in the galaxy group environment

PI Name: John Silverman

We aim to determine whether galaxy groups, a site of accelerated galaxy evolution and merging, are conducive for accretion onto supermassive black holes (SMBHs). We propose to observe 25 low-redshift (z~0.055) galaxy groups from the 2dFGRS with Chandra/ACIS-I for 10 ksec each to determine their AGN content (L_X>10^41 erg/s) unhampered by obscuration. We will determine whether external or internal processes are important drivers of SMBH growth by utilizing the full morphological information (e.g., bulge-to-disk ratio, asymmetry, tidal features) of AGN hosts available from the ZENS survey. Furthermore, we can determine how the environment regulates both AGN accretion and star formation in the intermediate potential wells of galaxy groups.

Title: Chandra deciphers the Optically 'Dull' X-ray Bright Galaxies at z~0.

PI Name: Anca Constantin

X-ray Bright Optically Normal Galaxies (XBONGs) are a rare puzzle in the AGN menagerie, showing AGN-like X-ray luminosity (logLx>42) but no optical line emission. Are they optically passive because of host galaxy dilution in the spectroscopic apertures? Obscuration by circumnuclear dust? Or are they instead X-ray bright due to radiatively inefficient accretion flows (RIAFs) which lack an ionizing UV bump? Or X-ray flaring? Or extended emission from hot gas? XBONGs to date have redshifts too high or S/N too low for reliable classification or detailed study. For a small carefully-vetted sample of local XBONGs from the SDSS and ROSAT All Sky Survey, we propose to use Chandra X-ray fluxes, morphologies, and spectra to test all 5 hypotheses.

Title: Investigating the Nuclear Activity of Barred and Unbarred Spiral Galaxies

PI Name: Leigh Jenkins

We propose to complete Chandra observations of a well-defined, well-matched sample of 32 nearby (d<70 Mpc) barred and unbarred spiral galaxies. Twelve galaxies are currently unobserved, and we request a total of 180ks of ACIS-S observations (15ks each) to complete this unique survey. The aim of this X-ray study is to search for low-luminosity AGN activity (down to 5e39 erg/s) that optical observations may have been unable to detect. In conjunction with uniform multiwavelength bar and nuclear morphology classifications, this will allow us to determine what effect the presence/absence of a bar/nuclear feature has on the detection and strength of the X-ray nuclei. This is the first X-ray study of its kind, and has great potential to shed light on the long-standing questions of AGN fueling.

Title: Determining the Nature of the Faintest Hard X-ray Selected AGN with Chandra

PI Name: Shanil Virani

We propose to complete the X-ray spectral characterization of our 3-Ms Ultra-Deep INTEGRAL Survey with Chandra observations of 5 faint AGN. Combining the Chandra and INTEGRAL spectra will allow us to fit for the absorbing column density and the intensity of the Compton reflection component, both fundamental parameters in understanding the AGN population. Deriving a correct census of heavily obscured AGN is the last piece of the puzzle, hampered by strong bias against detection in the 0.1-10 keV band. We have supporting multi-wavelength observations for all sources, critical to measure other source parameters like bolometric luminosity, re-radiated emission, black hole mass, etc.

We propose for two 25 ks ToO observations of blazars (or any other high latitude sources) undergoing an exceptional flare in the Fermi gamma-ray band. We intend to use Chandra only if observations with other facilities such as Suzaku or Swift are not sufficiently sensitive, or cannot reach the source because of the Solar angle or scheduling constraints. The resulting X-ray data - both the spectrum and variability information - will be indispensable to deterine the emission mechanisms, and by extension, allow inferences about the structure of the sub-parsec jet, and connection of the jet to the accretion disk and the supermassive black hole.

Title: Spent synchrotron lobes in giant radio galaxies: how much energy do they store?

PI Name: Katherine Blundell

We wish to make deep observations of giant radio galaxies having known X-ray emission extended along their radio axes, associated with the oldest part of the synchrotron lobes that straddle their respective active galactic nuclei. We wish to establish the spatial extent of these inverse Compton scattered CMB photons that give the observed X-rays since this emission traces the presence of particles with Lorentz Factor ~ 1000. This is an extremely important clue in establishing the so-called "low-energy cutoff", the Lorentz factor at which the particle energy distribution turns over at low energies: determining this is crucial for quantifying the amount of energy that these lobes store and can deposit in the IGM

The high resolution Chandra image will match the resolution of optical and radio structures observed in this source. The X-ray morphology will provide the critical information needed for studying physical conditions and understanding the impact of the evolving radio source onto the host galaxy environment.

Title: Chandra survey of Polar Broad Absorption-Line Quasars

PI Name: Kajal Ghosh

We have detected polar broad absorption-line quasars from their radio-core variabilities. Recent X-ray observations of two polar LoBALQSOs suggest that they may have different X-ray properties from other BALQSOs: their X-ray absorbing columns are much smaller compared to that of non-polar LoBALQSOs with Compton-thick absorbing columns and the polar LoBALQSOs may have different type of outflow. We proposed snapshot survey (6~ks exposure each) of 10 polar BALQSOs during Cycle~10 and only 3 BALQSOs were approved. Two of these three BALQSOs have been recently observed with Chandra and the results clear show that they are extremely luminous with no intrinsic absorption. Thus, we propose snapshot survey (6~ks exposure each) of rest 7 polar BALQSOs.

Title: After the Fall: Fading AGN in Post-starburst Galaxies

PI Name: Christy Tremonti

We propose joint Chandra and HST observations of an extraordinary sample of 12 massive post-starburst galaxies at z=0.4-0.8 that are in the short-lived evolution phase a few 100 Myr after the peak of merger-driven star formation and AGN activity. We will use the data to measure X-ray luminosities, black hole masses, and accretion rates; and with the accurate "clocks" provided by post-starburst stellar populations, we will directly test theoretical models that predict a power-law decay in the AGN light curve. We will also test whether star formation and black hole accretion shut down in lock-step, quantify whether the black holes transition to radiatively inefficient accretion states, and constrain the observational signatures of black hole mergers.
