Title: THE HIGHEST RESOLUTION CHANDRA IMAGE OF THE AGN-HOST INTERACTION IN NGC1068

PI Name: Giuseppina Fabbiano

We propose a 40 ks HRC exposure of NGC 1068, the prototype Compton-thick Seyfert 2 galaxy. We also propose to re-analyze the archival ACIS-S data with sub-pixel imaging to achieve the highest possible angular resolution. We will resolve the subarcsecond structures associated with the photoionized Narrow Line Region (NLR) clouds, and provide an unprecedented view of the interaction of the AGN winds and radiation with the surrounding interstellar medium (ISM). With these observations with will be able to (1) resolve X-ray emitting structures near the innermost ~100 pc of this galaxy, where the nuclear feedback is expected to be most intense, and where the ACIS data suffer from significant pileup; and (2) study in detail the disruption of the collimated inner radio jet.

Title: The Nature of Weak-Line Quasars at Low Redshift

PI Name: William Brandt

The SDSS has uncovered a remarkable class of radio-quiet quasars with no or extremely weak optical/UV emission lines. These have now been studied fairly well at high redshift (z = 2-6), but not at low redshift. We propose exploratory Chandra observations of 11 optically bright weak-line quasars (WLQs) at low redshift (z = 0.40-2.02) that will clarify the nature of this population. Specifically, we will determine if these low-redshift WLQs have "anemic" BLRs, or if instead they have relativistically boosted optical/UV/X-ray continua. The anemic-BLR explanation is favored for high-redshift WLQs, and we will determine if our targets represent the z < 2 extension of this population. We will also assess if WLQs show X-ray evidence for high Eddington-normalized accretion rates.

Title: Jet-ISM Interaction in the H2-Luminous Radio Galaxy 3C 293

PI Name: Patrick Ogle

We will observe the H2-luminous radio galaxy 3C 293 for 70 ks with the Chandra ACIS-S imaging spectrometer to study radio-jet feedback on the multi-phase ISM. 3C 293 displays extremely luminous H2 emission from 1E9 Msun of molecular gas at 150-1300 K, excited by jet driven shocks. Radio-jet driven neutral and ionized outflows are observed at the inner radio jet hot-spot. Star formation is suppressed by a factor >10 compared to what would be expected for a high surface density and large mass (1.5E10 Msun) of cold molecular gas. Chandra will measure the temperature, pressure, thermal energy content, and metallicity of the hot jet-shocked ISM, to help constrain models of H2 formation and negative jet feedback on star-formation.

We propose unconstrained 200 ks total ACIS-S observations of the merging, ULIRG, double-AGN galaxy NGC 6240, to map and measure the physical properties and metal abundances of the giant hot loops and halo. This hot extended component has an extraordinary LX ~1042 erg s-1, a luminosity often assumed to require AGNs. At a distance of ~100 Mpc, NGC6240 gives us the rare unique opportunity to witness directly phenomena that are thought to be common during galaxy formation at high redshifts.

Title: First X-ray observations of Low-Power Compact Steep Spectrum Sources

PI Name: Magdalena Kunert-Bajraszewska

We propose to study X-ray properties of Compact Steep Spectrum (CSS) radio sources with Chandra to look for spectral differences indicative of the radio source age. We selected a sample of CSS sources with lower radio power than the classic ones to be observed with Chandra for 70~ksec. All sources are embedded within their host galaxies and represent a different stage of the radio source evolution within the ISM. We will follow evolution of their X-ray properties by investigating the correlations between (1) the radio and X-ray luminosity, (2) and the absorption column and the radio source size; and significance of different emission components, e.g. thermal, reflection, emission lines in the high S/N X-ray spectra.

Title: Completing the Chandra 3C Snapshot Survey: Extragalactic Radio Sources with z < 0.3

PI Name: Daniel Harris

In the last decade we performed a series of HST snapshot surveys of the 3CR sample that proved to be extremely productive. As the completeness of high resolution X-ray observations is crucial for all multiwavelength analyses, we proposed a Chandra snapshot survey of all unobserved 3CR sources with z<0.3 in AO9, requesting half of the 64 targets. First results conform to expectations and this proposal requests the remaining 28 sources at 8ks each. This will yield detections of new jets, hotspots, and nuclei; the later relevant to evaluate the AGN unified models. The observations will also provide a versatile, complete, and uniform database that will be a valuable resource for the astronomical community, and since it is designed as a 'legacy' program, we waive proprietary rights.

Title: SPTIZER DISCOVERS THE MOST LUMINOUS AGN IN A TRULY BULGELESS DISK GALAXY? THE CHANDRA VIEW OF NGC 4178

PI Name: Shobita Satyapal

We propose to observe for 40 ks the nearby bulgeless galaxy NGC 4178, which is optically classified as a normal galaxy but has been recently discovered by Spitzer to show prominent high ionization [NeV] emission thus far exclusively associated in extragalactic sources with AGNs. If the AGN is confirmed in this object, NGC 4178 will be an exceptional source, in the league of NGC 4395, since it will be one of only 3 known completely bulgeless disk galaxies with a supermassive black hole. The exquisite spatial resolution and sensitivity of Chandra are necessary to confirm the presence of an AGN, disentangle its contribution from the host galaxy emission, constrain the intrinsic absorption, and estimate the bolometric luminosity of the nuclear region.

Title: X-ray and HST Imaging of Kpc-Scale Binary AGNs

PI Name: Yue Shen

Binary active galactic nuclei (AGN) with kiloparsec separations are of great value in understanding the role of galaxy mergers in AGN fueling and the interplay between supermassive black holes and their hosts. While pervasive in theoretical models, despite decades of searching, merging kpc-scale binary AGNs remain extremely difficult to find. Here we propose to observe four newly discovered, optically-selected kpc-scale binary Type 2 AGNs with Chandra and HST. The detection of two X-ray nuclei in each galaxy will confirm their binary AGN nature unambiguously, and triple the number of kpc-scale binary X-ray AGN known. The joint HST observations will explore host morphologies and small-scale star formation activity in these merging systems.

Title: Low luminosity AGN and low mass black holes in nearby dwarf galaxies

PI Name: Thomas Maccarone

We propose a 20 kilosecond observation of the Ursa Minor dwarf spheroidal galaxy and a 50 kilosecond observation of the newly discovered Leo T dwarf galaxy. These two objects represent our best hopes for finding intermediate mass black holes in the centers of Local Group dwarfs. Ursa Minor has an unusual radio source very close to its center position which is difficult to explain as anything but an intermediate mass black hole. Leo T has a gas density orders of magnitude higher than any other dwarf galaxy meaning that even a 200 solar mass black hole, as would be predicted from the M-sigma relation, would be detectable in 50 kiloseconds there.

Title: Where is the Site of TeV Flaring in M87?

PI Name: Daniel Harris

From 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 lightcurve for comparison with those obtained by the Cherenkov observatories.

Title: X-ray Properties of 2MASS Selected BALQSOs

PI Name: Xinyu Dai

BALQSOs may play a key role in AGN feedback. Their feedback efficiency depends on their covering fraction and average gas absorption. Recent studies have constrained the BALQSO covering fraction using a 2MASS selected sample. We propose to observe nine 2MASS selected, red BALQSOs to complement the archival X-ray observations that have only targeted optically bright, blue BALQSOs. By comparing the X-ray to K band flux ratios between these two samples, we will measure the average gas absorption of BALQSOs in an unbiased way. If the red BALQSOs contain significantly more dust and gas, the combined correction on the feedback energy can reach a factor of ~20 and BALQSOs could provide the minimum 5% feedback efficiency needed to explain the co-evolution between black holes and host galaxies.

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 421, 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 gamma rays. Our scientificc goal is to derive major 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. Study the morphology of the X-ray sources.

Title: Exploratory X-ray Monitoring of z>4 Radio-Quiet Quasars

PI Name: Ohad Shemmer

We propose to begin an exploratory X-ray monitoring project of the most distant quasars by obtaining one snapshot observation for each of four sources at z>4 in Cycle 12. Combining these observations with two archival X-ray epochs per source will provide basic temporal information over rest-frame timescales of 2-4 yr. We are supporting this project with Swift monitoring of luminous quasars at z=1.3-2.7 to break the L-z degeneracy. Continuing our monitoring project in future Chandra Cycles will ultimately serve as the benchmark for X-ray variability studies of quasars at the end of the `dark ages'. Our prime goal is to test claims that quasars were more X-ray variable in the early universe with implications for evolution scenarios of the central engine in active galactic nuclei.

Title: X-rays from the extended emission-line region of 3C305: probing a massive jet-driven outflow

PI Name: Martin Hardcastle

Outflowing extended emission-line regions driven by radio-galaxy jets are unusual phenomena in the local universe but are much more common at high redshift, where they may provide an important kinetic channel for AGN feedback. We have recently made the first detection of a low-redshift emission-line outflow in the X-rays, and have shown that the hot gas in this outflow dominates the energetics. We now propose observations of 3C305, probably the best-studied low-redshift radio galaxy in which the jets drive an extended outflow of both warm and cold gas. Our observations will allow us to constrain physical conditions (temperature, density, magnetic field strength) in the outflow and determine its energy budget, and will give us crucial insights into the nature of these systems.

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 nature of the low luminosity Seyfert 2 galaxy NGC 7590

PI Name: Xinwen Shu

Observations have detected a class of X-ray unabsorbed Seyfert 2 galaxies (NH<10^22 cm^-2). Interesting results have been obtained recently towards whether these sources may genuinely lack a broad-line region, in contrast to the standard unification model. However, only few objects have yet been securely identified. Seyfert 2 galaxy NGC 7590 was previously identified as X-ray unobscured based on ASCA data. New XMM images have shown its X-ray emission is dominated by extended component from the host galaxy and an off-nuclear ULX. The nature of the nuclear X-ray emission remains unclear due to strong contamination. With its superb spatial resolution, Chandra exposure would enable us the first time to detect the nuclear X-ray emission, and to measure the nuclear obscuration if existed.

Title: A celestial waltz: swirls and turbulence from radio galaxies in a rich group

PI Name: Diana Worrall

Though it is widely understood that radio galaxies heat the intergalactic medium (IGM), pictures of interactions have been hard to come by. High-quality mapping of the NGC 7016/7018 system has shown adjacent radio galaxies in this rich group interacting strongly with a ROSAT-detected hot atmosphere. Two remarkable 360-degree bends in the N radio jet of NGC 7016 appear to trace a collision between the jet and a vortex in the IGM. We see symmetric bends closer to the core, and buoyancy effects in the lobes of NGC 7018. These features point to likely sites of heating associated with the radio plasma and density irregularities in the IGM. We propose ACIS observations to study the dynamics and heating, so to assess the extent to which this phase of radio activity is disturbing the IGM.

Title: Direct Determination of Dark Matter Fractions and M/L in Elliptical Galaxies

PI Name: David Pooley

Sparsely sampled X-ray observations (every >=5 years) of stellar microlensing in quadruply gravitationally lensed quasars offer two powerful methods of determining the dark matter to stellar matter ratio in the lensing galaxies. The first is by measuring the frequency of caustic crossings over time. The second comes through treating these widely spaced observations as independent snapshots of the stellar content of the lensing galaxies and using them in a single-epoch analysis. The random motions of the microlensing stars in the lensing galaxies ensure that widely spaced observations will effectively sample independent rearrangements of the stellar content.

Title: Radio-loud feedback in Seyfert galaxies

PI Name: Judith Croston

Feedback processes from AGN and star formation are now thought to be an important ingredient in galaxy formation models, potentially solving the long-standing problem of explaining the deficit of galaxies at the low and high mass ends of the galaxy luminosity function relative to model predictions. Using Chandra we have recently found evidence for shock-related features associated with kpc-scale radio lobes in several Seyfert galaxies. Here we propose to observe two further, similar Seyfert radio sources so as to determine how common this mode of feedback is, and whether the impact of Seyfert outflows is linked to host galaxy properties and black hole mass.

Title: Exploring the X-ray Properties of the Highest-Luminosity Double-Peaked Emitters

PI Name: Bin Luo

We propose an exploratory survey of the X-ray properties of the highest-luminosity AGNs with double-peaked low-ionization broad emission lines. These luminous sources only have very limited studies in the X-ray regime, and they may have extraordinary X-ray properties. The double-peaked line-emitting mechanism is highly uncertain in the high-luminosity population. We selected six targets from SDSS DR 7 with higher luminosities and redshifts than most of the known double-peaked emitters, sampling the largely unexplored space of the luminosity-redshift plane. We will define the basic X-ray properties of these most-luminous double-peaked emitters, constrain models of the accretion-disk illumination structure, and probe the underlying physics that differentiates them from normal AGNs.

We ask for 80ks of HRC imaging observation to unambiguously resolve the X-ray emission, and unveil the nature, of two optical sources hosted by a galaxy in the COSMOS field (CID-42) and separated by only 0.495''. One of the two sources is the best candidate to date for being a recoiling super-massive black hole (SMBH) with both spectroscopic and imaging signatures, in a recently merged system. CID-42 is a possible ``Rosetta stone'' for the study of SMBH mergers that are believed to occur during galaxy-galaxy mergers. Is CID-42 (1) a GW recoiling SMBH from a recent merger or (2) a slingshot recoiling SMBH in a triple SMBH system? HRC imaging will decide clearly.

Title: Energy Dependent X-ray Microlensing

PI Name: Christopher Kochanek

We will use microlensing, where the stars in the lens galaxy magnify the accretion disk of a gravitationally lensed quasar, to improve estimates of the size of X-ray emission regions as a function of energy. While we have clearly detected energy-dependent microlensing, precision results require constraining the overall structure of the microlensing magnification patterns on the longer time scales (years) over which they vary. We focus on extending by two epochs the light curves of two ``active'' systems, RXJ1131-1231 and Q2237+0305, that show energy-dependent X-ray microlensing using integration times long enough to measure X-ray fluxes in 3 energy bands. These observations can only be done with Chandra because future X-ray observatories will lack the necessary angular resolution.

Title: Is the binary AGN in the galaxy pair UGC 08327 activating or quiescencing?

PI Name: Francesca Panessa

We propose to observe UGC 08327, one of the rare case of galaxy pair hosting a binary AGN. The optical spectra clearly classify both nuclei as type 2 Seyfert galaxies. The XRT/Swift data are limited in resolution and sensitivity, allowing a secure detection for only the brightest AGN. A 5 sigma estimate of the X-ray luminosity of the second one is consistent with an AGN origin. We request a 30 ks Chandra observation to definitely confirm the AGN nature of the weakest source and assess the obscuration level in both AGN. The spatial separation of the two merging galaxies is in between the activation and the quiescence AGN phases predicted by models, making UGC 08327 an ideal laboratory to investigate how the activity is triggered by massive mergers.

Title: A Systematic Chandra Survey of AGN in Major Mergers -- How many Binary AGN are out there?

PI Name: Kevin Schawinski

While we know of individual binary AGN in merging galaxies, there has been no systematic search for such systems that would allow us to determine the intrinsic frequency of binary AGN in mergers. Are such binary AGN phases intrinsically rare? Do the conditions in major mergers strongly favor accretion on only one black hole? More generally, what is the mix of star formation and AGN activity in major mergers, and how does that progress with the merger stage? In order to answer these questions, we propose to observe a sample of 24 local major mergers (z<0.055) selected from the Sloan Digital Sky Survey and the Galaxy Zoo project with Chandra+ACIS to search for binary AGN. Its superb spatial resolution makes Chandra the only X-ray facility able to resolve close binary AGN.

Title: The Circinus Galaxy: shedding X-ray light on the energetics of AGN outflows

PI Name: Beatriz Mingo

We propose a 180 ks observation of the Circinus galaxy, a nearby (4Mpc) spiral containing both a very bright Seyfert 2 nucleus and starforming regions, and with a pair of radio lobes spanning ~7 kpc. We have analysed a short (25 ks) Chandra exposure and have found striking evidence for interaction between the radio lobes and large-scale features in the X-ray emitting gas. With this long exposure we will be able to determine physical conditions in the rims of the Eastern and Western lobes, and calculate temperatures and pressures for the external regions of the galaxy, to evaluate the shock conditions. These results will enable us to calculate the total energy output from the AGN, estimate the source lifetime and see how they relate to the current models of AGN and galaxy evolution.

Title: X-ray follow-up of Seyferts with candidate dual supermassive black holes

PI Name: Brian Gerke

This proposal requests ACIS-S imaging (90 ks in total) of three Seyfert galaxies whose optical spectra suggest the presence of two AGN at kpc-scale separations (so-called dual AGN). Each target's AGN emission lines are double peaked, with the two peaks spatially offset by approximately one arcsecond (corresponding to 1--2 kpc). The aim is to determine whether these sources harbor two X-ray point sources coincident with the two optical emission regions. Detection of such a pair among our targets would establish a powerful new technique for identifying large numbers of dual AGN with optical spectroscopy. This would have important implications for understanding galaxy evolution and supermassive black hole growth and would help to constrain the parent population of LISA sources.

Title: A Definitive Observation of an Accretion Disk Wind in the Quasar MR 2251-178

PI Name: James Reeves

The bright, nearby QSO MR 2251-178 was the first AGN where a warm absorber was detected. Subsequent observations have shown there are at least two outflowing components; a low ionization soft X-ray absorber and a fast (0.07c), high ionization wind. We propose a deep (400 ks) Chandra HETG observation of MR 2251-178 in order to unequivocally determine the origin of the outflow at the highest possible spectral resolution. Our goals are; (i) establish the nature of the high ionization outflow, e.g. as part of a disk wind, through unprecedented high S/N observations in the Fe/Si K band, (ii) determine the properties of the soft X-ray absorber through high resolution spectroscopy and (iii) establish the connection between the UV and X-ray absorbers with a simultaneous HST snapshot.

Title: Chandra observations of unidentified Fermi sources detected by INTEGRAL

During its first year of activity Fermi/LAT detected 1451 sources, most of which have not been identified yet. Just few of these sources have been detected at lower energies by INTEGRAL IBIS/ISGRI. Using an optimized analysis method, we have re-processed all the public INTEGRAL data. From the resulting all-sky mosaic we found several possible ISGRI counterparts of LAT sources, and we selected six of them, all still unidentified, mostly located at high Galactic latitudes, and very likely new blazars. We propose Chandra/ACIS-I observations of these six sources aimed to refine their position and to reveal their nature. This would greatly increment our knowledges on the scarcely known population of hard X-rays and gamma-rays emitters.

Title: X-ray properties of the Youngest Radio Sources

Our main goals are to establish their X-ray properties, determine the origin of the X-ray emission, study properties of their environment and look for a division into two classes of radio sources FRI and FRII in the earliest stage of the radio source evolution. These young radio sources are in an important phase of a highly supersonic expansion and drive strong shocks into external medium. Such interactions are critical for 'feedback' that is not yet understood. The new X-ray data will allow for investigating the dynamics of such interactions in the youngest radio sources which are impacting directly the nuclear regions of their host galaxies.

Title: Extreme Velocity Quasar Outflows and the Role of X-Ray Shielding

PI Name: Fred Hamann

High velocity outflows are ubiquitous in quasars and possibly important for feedback to galaxy evolution. X-ray studies have shown that outflows with broad absorption lines (BALs) in the rest-frame UV also have strong X-ray absorption, but flows with only narrower "mini-BALs" are dramatically less X-ray absorbed. This disparity raises serious doubts about a key theoretical premise: that strong X-ray/far-UV shielding is needed to drive these flows radiatively to high speeds. We propose Chandra ACIS-S observations of 7 quasars that are matched to previous samples but with extreme high-velocity mini-BALs. Our observations will double the velocity range covered by previous work and thereby place new strong constraints on the acceleration physics and the role of radiative shielding.

Title: Chandra Survey of Hard X-ray Selected Merging AGN Hosts

PI Name: Richard Mushotzky

One of the fundamental questions about AGN is why a given source is active while another located in a superficially similar galaxy is not. A recent survey of nearby hard X-ray selected AGN has found a high rate of mergers (30%) compared to optically selected AGN (2%). Many of these systems contain multiple AGN that can only be detected with the high resolution of Chandra (as has been shown in previous observations of NGC 6240 and Mrk 463 which are members of our sample). We propose to follow up those systems with signs of disruption or multiple nuclei within 25'' which can only be detected with the resolution of Chandra. These data will provide a sample to determine the incidence of multiple accreting nuclei in mergers for the first time.

Title: THE FIRST SPATIALLY RESOLVED SPECTRUM OF AN AGN OUTFLOW IN AN EARLY-TYPE GALAXY: A DEEP HETG OBSERVATION OF MRK 3

PI Name: Daniel Evans

We propose a 300-ks HETG observation of the resolved, kpc-scale AGN outflow that forms the photoionized NLR in the prototypical early-type galaxy Markarian 3. We will use Chandra's superb spatial and spectral resolution to extract, compare, and model spectra at four off-nuclear points along the NLR and ENLR. By performing a detailed modeling of the emission-line spectra, we will determine (1) the spatial extent of the outflow, (2) its velocity structure, and (3) the mass and energy rates imparted by the outflow into its environment. Our results will provide the first X-ray test of whether outflows in such early-type galaxies expel, as expected, significant quantities of material during their hosts' transition from the blue cloud to the red sequence.
