Title XMM-Newton Constraints on the AGN Receding Torus Model


DOI 10.5270/esa-8j0w1tt
Author Dr Franz Bauer
Description Recent optical and mid-IR constraints suggest that the putative torus surrounding Active Galactic Nuclei (AGN) may recede with increasing AGN power. Such a result, if true, has important ramifications on AGN unification and the evolution of supermassive black holes (SMBHs). Surprisingly, the bulk of the high-z QSOs used to establish this result lack X-ray constraints. We therefore propose XMM-Newton observations for this otherwise robustly-studied sample to address several remaining questions. The resulting X-ray constraints will be compared to existing [OIII] and 6um AGN continuum luminosities to yield the most robust constraints on potential luminosity dependencies to date.

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.
