Description SgrA* is the ideal target to understand the accretion and outflow physics in the case of extremely low accretion rate onto a supermassive black hole. The discovery of flares from SgrA* has provided new exciting perspectives for understanding the processes at work in the Galactic nucleus. They are very likely to be produced within 10 Schwarzschild radii and hence probe the environment very close to the black hole. Recently, VLBI observations at 1.3mm demonstrate that angular resolution comparable to the apparent size of the event horizon is now technically possible. Therefore, we propose to perform simultaneous observations of SgrA* with XMM-Newton and 1.3mm VLBI to constrain the location of the high-energy flares from SgrA*.

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.
