Title XMM-RM: Quasar Accretion Physics in the Reverberation-Mapping Field


DOI https://doi.org/10.5270/esa-sh2r9tx
Author Dr Paul Green
Description To study the cosmic history of accretion, two reliable measurements are crucial: black hole mass and bolometric luminosity. Our SDSS Reverberation Mapping (RM) program is the first multi-object spectroscopic RM campaign, providing significantly improved BH mass estimates for a large sample of quasars to redshift 4 in a single field of 7 square degrees. Now with XMM-Newton, we will characterize the X-ray emission for about 700 of these quasars, enhancing measurements of bolometric luminosity and therefore Eddington ratio. From X-ray brightness, power-law slopes, and variability characteristics within the sample, we will also test accretion models in correlations that extend across the mass range, from Galactic X-ray binaries to quasars.

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.
