Abstract	The interaction of the nearby galaxy pair, NGC 4485 & 4490 (d=7.8 Mpc), has ledto enhanced star formation in the galaxies, and hence enhanced X-ray activity.The most remarkable feature of this is a population of at least sixultraluminous X-ray sources (ULXs). Here we propose two new 40-ks XMM-Newtonobservations, with the primary aim of studying these extraordinary sources. Thedepth of the proposed observations will be sufficient to place constraints onthe presence of a cool disk in their X-ray spectra, and on the presence ofshort-term variability, whilst extending the baseline of observations tocontinue long-term spectral and temporal variability studies. We will alsodetect sufficient counts to study the extensive diffuse X-ray emission of this system.

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.
