|Title||Simultaneous X-ray-VLA monitoring of NGC 253|
|Author||Dr Thomas Maccarone|
|Description||We propose 5 observations of 10virgulkiloseconds each with XMM and Chandra of the nearby star-forming galaxy NGCvirgul253. We plan to take these data simultaneously with data from the Very Large Array. This will give us a sample of several bright X-ray sources at a known distance with simultaneous radio coverage for the first time. Simultaneous monitoring experiments are necessary for understanding the relation between X-ray and radio luminosities at the poorly understood bright end of the luminosity distribution, and going to other galaxies should greatly increase the sample size of sources at these luminosities.|

|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.
