Description We propose a 100ks observation of the nearby galaxy M51, which hosts nine ULXs and a low luminosity AGN. The primary purpose of our observation is to confirm the periodicity of about 6000s from an ULX and iron line from another ULX in M51, as suggested by earlier short X-ray observations. The proposed 100ks observation will decisively establish the presence of both periodicity and iron line, and enable us to make a detailed study of these features and to search for similar features in other ULXs. Our observations will also provide power density spectra of ULXs, and enable us to detect possible presence of breaks at certain frequencies that will directly establish if ULXs are intermediate mass black holes. The single observation will yield a wealth of information on the nature of nine ULXs.

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.
