Abstract | We request a deep (250 ksec) XMM-Newton observation of a field that benefitsfrom the deepest multi-frequency radio observations currently possible to studythe AGN bright and radio feedback modes across cosmological times. The selectedfield also benefits from deep Spitzer, near-infrared, and optical data andmoderate X-ray data from Chandra. With the proposed observations we willdiscriminate between cold and hot gas accretors among radio and X-ray selectedAGNs to constrain the evolution of the two AGN feedback processes. A series ofadditional topics will be also addressed: X-ray variability vs radio, infrared,and optical spectral properties; the X-ray properties of various extreme andrare sources; and we will search for heavily absorbed radio-selected AGNs. |

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. |
