Operations CXO Status Report

Friday 9 January 2004 9.00am EST

During the last week Chandra completed the observing schedule as planned.

Chandra media telecon was held on Apr 24 describing observations of the inner regions of nine elliptical galaxies that allow estimates of the rate at which gas is falling toward the galaxies' supermassive black holes. These data also provide an estimate of the power required to produce radio emitting bubbles in the hot X-ray gas. Surprisingly, the results indicate that most of the energy released by the infalling gas goes, not into an outpouring of light as is observed in many active galactic nuclei, but into jets of high-energy particles. For full details see:

An image release was also issued on Apr 24 in conjunction with Hubble and Spitzer in celebration of the 16th anniversary of the Hubble mission. The spectacular image of M82 can be seen at:

The schedule of targets for next week is shown below and includes an observation of PKS 2155-304 coordinated with the XMM and Suzaku.
