Title Searching for dust obscured AGNs in extremely red objects

Description The nature of extremely red objects (EROs, R-K > 6) dicovered in deep optical and near-infrared imaging surveys is currently unknown. They could be either high redshift dusty starburst galaxies or old elliptical galaxies or dust obscured AGNs. We propose a pilot XMM observation of a small sample of EROs to search for the hard X-ray emission expected if these objects host hidden AGN. This is the most stringent test to verify or to discard the AGN hypothesis.

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.
