Joint Chandra/XMM/EVLA Monitoring of the Gas Cloud G2 as it encounters SGR A*

A dense, cold cloud (G2) is on a collision course with Sgr A*, the radio sourceat our Galactic Center. G2 is on an eccentric orbit and already shows signs oftidal disruption by the black hole. Highenergy emission from Sgr A* will likelyincrease significantly due to this encounter, peaking at pericenter (summer2013). We propose simultaneous Chandra, XMM, and EVLA monitoring observations toconstrain the rates and emission mechanisms of faint Xray flares, study theradiation properties of Sgr A* as G2 breaks up and feeds gas to the centralaccretion flow, and detect G2 itself as it is shocked and heated. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
