Abstract We propose XMM observations of 7 GALEX-selected compact Ultraviolet LuminousGalaxies (UVLG). These low-redshift UVLGs have properties very similar todistant Lyman Break Galaxy (LBG) populations, strongly suggesting that they arelocal analogs to LBG. These seven UVLGs are in the composite portion of the BPTdiagram indicating they are likely candidate AGN. These observations willdetermine whether there is an AGN dominating the X-ray emission in these UVLGs,which would contrast them to high redshift LBGs where X-ray detected AGN arerare.

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.
