Description Low surface brightness galaxies (LSBs) might appear optically unimpressive, but the largest LSBs contain as many stars as the largest normal elliptical and spiral galaxies. Very little is known about their X-ray properties. We propose short XMM-Newton observations of three giant, bulge-dominated LSBs that cover over a factor of four in K-band luminosity to create the first X-ray LSB sample, and compare their L_X-L_K scaling relation with normal early-type spiral bulges-ellipticals. We will also search for AGN in the nuclei and ULXs in the faint disks of these intriguing systems.

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.
