| Description | We propose to obtain XMM observations of 22 sources from the 24micron FLS Spitzer survey. The proposed targets have very high optical depths of silicate absorption at 9.7 micron, suggesting that such sources are hosting a black hole that is enshrouded in a compact dust distribution. The XMM observations will determine the amount of X-ray absorption directly, through X-ray spectroscopy, or via the X-ray to mid-IR luminosity ratio. In analogy with nearby galaxies which show high 9.7 micron optical depths it is highly probable these sources will comprise of a high fraction of heavily obscured nuclei. Then our observations may provide the pathfinder for the detection of the elusive population of Compton thick sources at high redshift where most of the energy of the XRB is produced. |

| 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. |
