Astronomy Colloquium
The SWIFT Bat Hard X-ray Survey- A New Window on the Local AGN Universe
Date: Tuesday, October 21st
Time: 3:30 pm
Place: 6515 Sterling Hall
Speaker: Richard Mushotsky, Goddard Space Flight Center/NASA
Abstract: The Swift Burst and Transient telescope (BAT) has surveyed the entire sky for the last 3.5 years obtaining the first sensitive all sky survey of the 14-195 keV sky. At high galactic latitudes the vast majority of the detected sources are AGN. Since hard x-rays penetrate all but Compton thick obscuring material (Column densities of 1.6E24 atms/cm2) this survey is unbiased with respect to obscuration, host galaxy type, optical , radio or IR properties. We will present results on the broad band x-ray properties, the nature of the host galaxies, the luminosity function and will discuss a few of the optical, IR and x-ray results in detail.<br>
