Title A Search for Unusual X-ray Properties in High-z, High-Accretion Rate Quasars


DOI 10.5270/esa-sprdm6g
Author Dr Ohad Shemmer
Description We propose to observe four of the most luminous quasars known, which have extremely high accretion rates and are at redshift ~2-3, using XMM-Newton EPIC PN and MOS with a total integration time of 135 ksec. We will obtain accurate measurements of the spectral slope in the quasars. ~1.5-20 keV rest-frame band and look for X-ray variations. Our prime goal is to test whether the X-ray spectral slope is an accretion-rate indicator for all AGN. Steep X-ray spectral slopes may identify our sources as the long sought high-redshift analogs of narrow-line Seyfert 1 galaxies.

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.
