A population of Dust Obscured Galaxies (DOGs; (F(24um)/F(R)>1000 and F(24um)> 1mJy) at z>1, likely associated with an obscured phase in the quasar lifetime,has recently been revealed. Redshift distribution, broad-band photometry andbolometric luminosities of DOGs indicate that these systems may represent anearly dust-embedded phase of powerful AGN activity. Due to low space density,DOGs are rarely detected even in the deepest X-ray surveys. However, low-qualityX-ray spectroscopy has revealed the common presence of highly obscured AGN intheir nuclei. XMM-Newton is the ideal telescope to study their largelyunexplored X-ray properties. We propose here to obtain a high signal-to-noiseX-ray spectrum for two unique, optically-identified DOGs from the Bootes survey.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
