|Title||The X-ray Baldwin Effect: z=2 Fe-K and Compton Humps as Ionized Disk Diagnostics|
|Author||Dr Martin Elvis|
|Description||By observing 4 bright radio quiet zvirgul2 quasars we propose to test the X-ray .Baldwin Effect.: that the relativistically broadened Fe-K line becomes weaker as AGNs become more luminous. This needs to be done with radio-quiet quasars to avoid beaming dilution. We will also test the proposed explanation of this effect: that the accretion disk becomes fully ionized. this can be done by measuring the Compton hump relative to the Fe-K line, since Compton scattering operates independent of ionization. To measure the Compton hump with XMM EPIC requires zvirgul2. The 4 proposed quasars have exposure times chosen to give 3sigma limits 1-10 of the low luminosity values, assuring an unambiguous result.|

|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.
