Abstract | AGN feedback is a key ingredient in modern galaxy formation models, invoked tosuppress star formation (SF) activity in early-type galaxies at recent epochs.However, the physics of this process is not well understood and poorlyconstrained by observations. Compelling observational evidence for its mereexistence has been missing so far. We identified a sample of early-type galaxiesin SDSS that define an AGN feedback sequence transitioning from SF via AGN toquiescence. We propose observations on a sub-sample of 18 targets characterizingthe AGN feedback process. These data will provide critical information about thepresence and significance of black hole activity in this sample, providingdeeper insight into the physics of AGN feedback in early-type galaxies. |

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. |
