Title Studying X-ray cooling in a luminous cluster with feedback

Author Dr Jeremy Sanders
Description We propose a 130ks observation of the X-ray brightest cluster above z=0.1, PKS0745-191. In the absence of heating there should be cooling at 1000 Msun-yr. XMM shows the presence of central cool gas and Chandra the location of feedback. We will examine the central temperature distribution with RGS to study the feedback-cooling connection. In addition, most of r_200 can be studied in a single pointing to examine clumping. We will examine the surface brightness fluctuation spectrum as a function of radius to connect to cluster-wide and AGN-related turbulence.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
