Description Supermassive black holes (SMBHs) in dwarf galaxies are crucial for our
understanding of the origins of SMBHs . While recent studies have found optical
signatures of AGNs in a growing population of dwarf galaxies, these studies are
biased toward redder galaxies with super-solar metallicities. This is a severe
limitation, since the premise behind the use of dwarf galaxies to probe seed
black holes rests on the assumption that they have had a quiescent cosmic
history, free of mergers or tidal stirring that would drive gas to the center
and fuel star formation and grow the SMBH. Optical studies therefore target the
wrong demographic. In this pilot study, we propose to observe with XMM-Newton a
new sample of low metallicity dwarf galaxy candidates with mid-IR evidence for AGN activity.

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.
