Description | Recent surveys discovered that 50% of AGN are hosted by massive galaxies with luminosities and colors typical of ellipticals-S0s. These findings defy the paradigm of ..local AGN=Seyferts in blue galaxies., which held for the last 30 years. How do these systems differ from classically-selected AGN? We propose EPIC observations of 7 z<0.1 AGN, selected in an unbiased way at energies > 10 keV with Swift BAT in early-type hosts. Carrying the imprints of the conditions of matter in the inner accretion flow, medium-hard X-ray observations are essential to unveil the true nature of these systems. |

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. |
