Title X-ray Spectral Statistics of a Complete Hard X-ray-selected AGNs

Author Dr Takamitsu Miyaji
Description We are compiling broad-band X-ray spectral properties of a complete hard X-ray selected AGNs. The sample consists of 31 Piccinotti et al. AGNs from the HEAO-1 A2 survey and additional 26 AGNs from ecliptic pole regions of the HEAO-1 A1-A3 based MC-LASS Catalog. Many of these AGNs have been observed by ASCA and we have initiated a program to complete high-quality broad-band spectroscopy of rest of the sample AGNs. Our ASCA AO-7 proposal was successful to obtain 5 of them. In this proposal, we request snap-shots of 5 remaining AGNs. Using the complete sample, we intend to study the distribution of intrinsic absorption, fraction of AGNs with warm absorber and intrinsic-luminosity - absorption correlation as key bright-end constraints to the Cosmic X-ray Background synthesis modeling.

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.
