|Title||Probing AGN feedback in early-type galaxies|
|Author||Dr Francisco J. Carrera|
|Description||AGN feedback is a key ingredient in modern galaxy formation models, invoked to suppress star formation (SF) activity in early-type galaxies at recent epochs. However, the physics of this process is not well understood and poorly constrained by observations. Compelling observational evidence for its mere existence has been missing so far. We identified a sample of early-type galaxies in SDSS that define an AGN feedback sequence transitioning from SF via AGN to quiescence. We propose observations on a sub-sample of 18 targets characterizing the AGN feedback process. These data will provide critical information about the presence and significance of black hole activity in this sample, providing deeper insight into the physics of AGN feedback in early-type galaxies.|

|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.
