Title Study of the Soft Excess - Warm Absorber in a Sample of AGN


DOI 10.5270/esa-y30orc9
Author Dr Martin Turner
Description GT-A sample of AGN showing structure in their soft X-ray spectra is to be observed. The physics of the spectral structure may be 1) a soft excess component above the underlying power law, possibly from the emission of the accretion disk, or-and 2) selective absorption due to a warm absorber. The candidate objects have been selected by a systematic study of ROSAT PSPC spectra in comparison to hard (2-10 keV) spectra measured by HEAO-1, EXOSAT or Ginga.

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.
