We propose 5 observations of 10virgulkiloseconds each with XMM and Chandra of thenearby star-forming galaxy NGCvirgul253. We plan to take these data simultaneouslywith data from the Very Large Array. This will give us a sample of severalbright X-ray sources at a known distance with simultaneous radio coverage forthe first time. Simultaneous monitoring experiments are necessary forunderstanding the relation between X-ray and radio luminosities at the poorlyunderstood bright end of the luminosity distribution, and going to othergalaxies should greatly increase the sample size of sources at theseluminosities.

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.
