Low surface brightness galaxies (LSBs) might appear optically unimpressive, butthe largest LSBs contain as many stars as the largest normal elliptical andspiral galaxies. Very little is known about their X-ray properties. We proposeshort XMM-Newton observations of three giant, bulge-dominated LSBs that coverover 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 spiralbulges/ellipticals. We will also search for AGN in the nuclei and ULXs in thefaint disks of these intriguing systems.

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.
