Title Monitoring the awakening of the dormant SMBH at the center of our galaxy

Description The recently discovered G2 dense dusty gas cloud, infalling towards the dormant SMBH at the center of our galaxy SgrA*, should reach its pericenter in September 2013. The X-ray luminosity of SgrA* is expected to increase significantly at this period and the fragmentation of this cloud should lead to an enhanced activity period over several months-years. Therefore, we propose a large program to monitor SgrA* during the course of the G2 cloud near its pericenter passage and after this event, combining the XMM-Newton high-throughput with several multi-wavelength observations with ground-based telescopes and satellites. This will offer us an unique opportunity to study accretion events on a dormant SMBH and its (re-)activation process.

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.
