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

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. |
