|Title||Testing the effect of quasar-mode feedback on the intracluster medium|
|Author||Dr Matt Hilton|
|Description||We propose to obtain XMM-Newton EPIC observations of the massive galaxy cluster ACT-CL J0320.4+0032 at z=0.384. We have recently identified that the Brightest Cluster Galaxy hosts a Type II quasar - one of only a handful of such systems to be discovered. This presents a rare opportunity to study the effect of quasar-mode feedback on the intracluster medium (ICM). We will address this by using the XMM observations to measure the temperature, entropy, and metallicity profiles of the cluster, and compare these to well-studied representative cluster samples and the results of numerical simulations. These observations will complement our 50 ksec Cycle 17 Chandra observation, the goal of which is to search for cavities in the X-ray emission.|

|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.
