12:45 -2.15 PM

       23.01. X-ray Spectroscopy of Photoionized Plasmas by Timothy R. Kallman	
       23.02. Collisional and Shocked Plasmas at High Dispersion by Marc Gagne

       Poster Review

       CXC team members will also be on hand during this session to answer
       questions concerning Chandra gratings data analysis.

34. Chandra X-ray Data Analysis -  Wednesday, 12.30 - 2PM

       34.01. Updates on Chandra Data Analysis and Calibration Database by 
Jonathan C. McDowell
       34.02. The CIAO 4.0 Data Analysis System by Aneta Siemiginowska
       34.03. A Common Question From The Chandra Help Desk: 
	      How Do You Combine Or Merge Observations? by Douglas Burke
       34.04. The Chandra HelpDesk by Elizabeth C. Galle

       CXC team members will also be on hand during this session to answer
       questions concerning Chandra data analysis.

Please check the Final Program for details:

CIAO4 Software Demos

The CXC team will have demonstrations of the CIAO4 software in the
Chandra booth during the entire meeting and can answer questions
related to Chandra data analysis. Participants are welcome to stop by
and try it out.

Item  2.  CIAO Patch

The CIAO team is planning a patch (CIAO 4.0.2) to support the
Mac OS 10.5 (Leopard) operating system on Intel Macs.  Several 
software changes to ChIPS & Prism and the latest versions of 
DS9 and XPA are required. 

The patch is scheduled for release in mid-April.

Item  3.  Chandra Calibration Team Position   

The Chandra Calibration Team has an opening for an IT Specialist 
(SAO Job#28-16).  The group analyzes both space-based and 
ground-based data relating to Chandra instrument performance, 
provides quantitative calibration information and documentation, 
and interfaces with external Chandra elements, including the 
scientific community.  Primarily, the Data Specialist will be 
involved in software development related to instrument performance 
for the Low Energy Transmission Gratings instrument, developing 
and analyzing numerical algorithms, data reduction and analysis, 
documenting and organizing results, and participating in the daily 
operations of one of NASA's Great Observatories, the Chandra X-ray 

Beyond a strong interest in hands-on participation in the operation 
of a major space observatory, qualifications include a solid 
background in physics, math, astronomy, and computing.  Positions 
of this kind often have been an excellent learning opportunity for 
recent holders of baccalaureate degrees looking for several years' 
experience before proceeding to graduate school, but also have been 
filled by persons with a variety of other backgrounds and planned 
career paths.  If interested, please respond to the announcement 
for Job #28-16 at http://cfa-www.harvard.edu/hr/postings/28-16.html 
or contact Jeremy Drake (jdrake@cfa.harvard.edu) directly.

Item  4.  EPO Updates  

Check out "The Beautiful Universe":  Chandra's high-definition  
podcast is a new feature and a way to see Chandra images at their  
finest.  This podcast is meant to be viewed on the big screen. 
Or subscribe through iTunes Music Store 
The Beautiful Universe (Chandra in HD) debuted at #5 in the iTMS Top  
Science & Medicine Podcasts

Chandra images are now featured in Google Sky:  Google Sky lets you tour  
Chandra images online. Just like in Google Maps you can pan, zoom and  
search. Take a tour of the Chandra layers and try adjusting the  
transparency to see how the images fit into the optical map underneath.

Item  5.   Conference: The Warm & Hot Universe  

*   "The Warm & Hot Universe"
*  http://warmhot.gsfc.nasa.gov
*  http://www.astro.columbia.edu/~frits/WarmHot_Columbia.html
*       May 7-9, 2008
*       Columbia University
*       New York City

A workshop on the unique contributions of X-ray astronomy to the  
understanding of large scale structures and the Universe.

Important Dates:

March 26th: Abstract deadline for contributed talks and posters
April 10th: Early registration ($350; $250 for students) ends; late  
registration is $400 ($300 for students)

Important Note Regarding Hotels:

The conference organizers have reserved blocks at a number of  
Manhattan hotels at various distances from the conference site at  
Columbia.  See the website link


for more information.  Due to a number of conventions in town during  
the meeting, hotel rooms are at a premium and we recommend making your  
reservations as soon as possible.

.  Main topics to be covered include:

     * Missing baryons at low redshift and in clusters
     * The Warm Hot Intergalactic Medium (WHIM)
     * Non-thermal heating, cosmic feedback, excess Entropy and Li-6
     * Thermal and non-thermal cluster soft X-ray excess; the hard  
     * Evolution and scaling properties of clusters
     * Sunyaev-Zel'dovich surveys
     * X-ray gas parameters of groups and their evolution
     * Mass profile of groups
     * AGN surveys and galaxy formation
     * Interstellar and interplanetary medium.
     * Particle acceleration and interactions in the heliosphere.
