Title X-Ray Luminosity--Mass Relation and AGN Feedback in Galaxy Groups

Description Most of the mass, most of the baryons, and most of the galaxies in the Universe are in galaxy groups. The processes connecting cooling gas in the hot inter- galactic medium and feedback from AGN are more easily observed in groups than in clusters because of their shallower potential wells. A precise characterization of the X-ray luminosity-mass relation over a large mass range is today.s single most important task to ensure that the full cosmological power from the 100000 groups and clusters to be detected with eROSITA can be exploited. We will use a complete sample of almost 90 galaxy groups and clusters to constrain cooling and feedback mechanisms as well as the Lx-M relation. Observations for all clusters are available. With this short proposal we aim to complete observations for the group sample.

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.
