Abstract The observation of time varying Fe Ka line emission at 6.4 keV in severalregions in the central 100 pc is strongly suggesting that the SMBH experienced aperiod of more intense activity in the relatively recent past. The observationof these echoes can provide invaluable information on the last high state of SgrA* and its duty cycle, on the matter distribution in the region and on thechemistry induced by these intense emissions. We propose to perform a deep scanof the molecular matter in the central degree with XMM to build the lightcurveof Sgr A* over the last centuries thanks to the time dependent morphology of the6.4 keV line emission. This deep scan will also contribute to settle otherissues such as the .hot plasma..

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
