|Title||UNVEILING THE NATURE OF HARD X-RAY SELECTED AGN THROUGH XMM-NEWTON SPECTROSCOPY|
|Author||Dr MARCELLA BRUSA|
|Description||We propose a 80 ks observation of a sizeable sample of rather peculiar AGNs detected in the 2-10 keV band by the HELLAS2XMM survey in the PKS0537-28 field, for which extensive multi-wavelength follow-up observations (radio, IR, optical and Chandra) have already been obtained. This sample comprises red quasars, candidate Type 2 quasars, optically blue, X-ray absorbed quasars, extremely red objects, and sources characterized by large X-ray-to-optical flux ratios. The primary goal of this proposal is to obtain good quality X-ray spectra of a r^ant number of sources in order to measure key parameters such as X-ray column density and iron K_alpha emission lines, and to investigate the link between the X-ray and optical properties.|

|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.
