|Title||Are the SCUBA deep survey sources starbursts or AGN|
|Author||Dr Walter Gear|
|Description||We propose to make 50 kilosecond images of two fields for which we have deep SCUBA 850 micron images which have revealed a large number of highly luminous dusty galaxies. These galaxies appear to be similar to IRAS-selected Ultra-luminous objects, and if powered by star-formation then a significant fraction of all stars ever formed formed in these sources. It is also possible however that these galaxies are are in fact examples of obscured AGN, as have been postulated to contribute a large fraction of the X-ray background at high energies. The proposed observations will test which of|

|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.
