Flaring Activity of Sgr A* During the Passage of the G2 Cloud
Résumé
Preliminary results of our monitoring of Sgr A* in coordination with Chandra, XMM and HST will be presented. The main focus will be on the cross correlation analysis of radio and X-ray flare emission on September 12, 2013 when a luminous X-ray flare was detected by Chandra. The peak of flare emission at 3.5cm was found to be delayed by more than 130 minutes when compared to the peak of the X-ray emission. The cross correlation of the peak emission at radio and X-rays is consistent with an adiabatic expansion modelof flare emission.
