| ABSTRACT | |
| We propose 12 XMM observations of 40ks each to survey the CMZ and capture the echoes of SgrA*'s past flares as they propagate in this region. Since XMM last observed the central 200pc, these events have been scanning the molecular distribution along the line of sight. The deep survey we propose will therefore probe the time variability of all known reflection features. Using the description of SgrA*'s past flares, in terms of age and duration, we will then pair each feature with its illuminating event and therefore give a line-of-sight position for all illuminated clouds. Combined with existing kinematics information, the new XMM survey will fully constrain the dynamical description of the CMZ, providing the first unambiguous 3D model of the region. | |
