|Title||A Black Hole in BG Geminorum?|
|Author||Dr Mark Reynolds|
|Description||We propose to observe the Galactic black hole candidate BG Gem with EPIC onboard XMM-Newton. A detection of this system at a luminosity greater than or equal to 10^31 erg s^-1 would significantly bolster the case for the presence of a stellar mass black hole primary. If confirmed, then BG Gem would be the black hole binary with the longest orbital period (by a factor of 3), in addition to being the only eclipsing Galactic black hole binary system.|

|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.
