Abstract | Central galaxies in rich clusters are the sites of cluster cooling flows, withlarge masses of gas cooling through part of the X-ray band. Many of thesegalaxies host powerful radio sources. These sources can displace and compressthe X-ray gas leading to enhanced cooling and star formation. We proposeobservations of three bright cooling flows with radio sources that will exploitthe large collecting area and spectral resolution of XMM-Newton. We willconstrain the source of additional pressure in radio holes in the X-rayemission needed to support overlying shells of X-ray gas. We will address theproblem of the lack of kT < 1-2 keV gas in cooling flows by searching forabundance inhomogeneities, heating from the radio source, and excess absorption. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
