Title Searching for Nearby ULXs in HST Imaged Galaxies

Author Prof Philip Kaaret
Description We propose to survey 11 nearby galaxies with XMM to search for new ultraluminous X-ray sources (ULXs). Most ULXs are associated with star formation and are likely stellar mass black holes in super-Eddington accretion states or with mildly beamed emission. Some of the strongest intermediate mass black hole (IMBH) candidates are found in galaxies with low star formation rates (SFRs). Our survey will sample late-type galaxies with low SFRs that lack deep X-ray data but are covered by archival Hubble Space Telescope observations enabling us to identify optical counterparts and study the surrounding environments.

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.
