|Title||Understanding X-ray Emission from AGN in Low Surface Brightness Galaxies|
|Author||Dr Harsha Raichur|
|Description||We propose for XMM-Newton observations of 6 nearby, bulge dominated giant low surface brightness (GLSB) galaxies. They have diffuse stellar disks and massive HI disks but are overall poor in star formation. They are possibly the most dark matter dominated spirals in our nearby universe and yet a significant fraction of them have prominent bulges that host AGN activity. Optical studies indicate that their AGN black hole masses are low compared to their galaxy masses and lie below the M-sigma correlation. Not much is known about the AGN activity and bulge evolution in these galaxies, especially in the X-ray domain. Our proposed XMM-Newton observations will be used to detect and characterize the X-ray properties of these 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.
