Title X-ray continua of radio-quiet quasars: Testing accretion disk models. SSC_6


DOI 10.5270/esa-op88k2k
Author Dr Michael Watson
Description We propose to measure the spectra of bright radio-quiet quasars, using the XMM EPIC pn and MOS detectors. The objects are taken from a sample which we have already previously studied using the ROSAT PSPC detector. All objects are prominent radio-quiet quasars which have already been studied extensively in the optical and X-ray spectral range. The high statistical significance of the XMM spectra will for the first time permit us to separate different soft and hard emission components based on contemporaneous data taken with the same instrument. In particular, using an accretion disk model code, developed by us, it will be possible to determine the properties of their accretion disks which are thought to contribute most of the emission in the soft X-ray range.

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.
