Description Building on the great successes of the monitoring program of Sgr A* flaring
activity we initiated and fostered in the last years, we propose to continue
extended observations of the Galactic nucleus with XMM-Newton in order to
further test the supermassive black hole paradigm while studying the accretion
flow and radiation mechanisms associated with this unique system at the centre
of the Galaxy. Thanks to the unique capabilities of XMM-Newton we will tackle
crucial questions that remain unanswered: 1) are X-ray flares from Sgr A* caused
by blobs of hot, orbiting plasma in the accretion flow close to the event
horizon of the black hole,

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.
