Description The X-ray spectral analysis of Compton thick (CT-) active galactic nuclei (AGN)
represents a fundamental step to understand the physics of the obscuring
material surrounding accreting supermassive black holes. We propose to target
with a combined NuSTAR/XMM-Newton observation two candidate CT-AGN selected from
the BAT 100-month volume-limited (z<0.03) sample. Thanks to the excellent count
statistics, we will be able to constrain several spectral parameters (e.g.,
relative importance of the scattered component versus the direct one, geometry
of the obscuring torus, equivalent width of the Iron emission line). This
analysis will refine our knowledge of the selection function of CT-AGN,
therefore helping us in determine the true intrinsic fraction of CT-AGN and their contribution to the CXB.

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.
