Swift XRT/UVOT follow-up of Fermi J1717-5156 after a gamma-ray flare
Abstract
Following the Fermi-LAT detection of a flare on April 7, 2012 from Fermi J1717-5156, a new gamma-ray source near the Galactic Plane (ATel #4023), we obtained Swift observations on April 9, 11, and 13. These observations confirm that the radio source found within the LAT error circle, PMN J1717-5155, is also in a high X-ray and optical state.
A new X-ray source consistent with the radio position of PMN J1717-5155 is well detected in each XRT observation with 10, 4.6, 2.7 ks exposures, respectively.- Publication:
