Detection of an Unidentified Extended Gamma-ray Source Close to the Galactic Supernova Remnant 3C 400.2
Abstract
A new extended gamma-ray source (PS J1934.5+1845) was detected with a significance of $\sim$13$\sigma$ at a location of 1$^{\circ}\!\!$.83 away from the radio location of the Galactic supernova remnant 3C 400.2 using about 9 years of Fermi-LAT data. The 68% containment radius of PS J1934.5+1845's extension was found to be 0$^{\circ}\!\!$.61 and PS J1934.5+1845 is showing a power-law type spectrum with a spectral index of $\sim$2.38. In this presentation we will summarize the gamma-ray analysis methods and report on the analysis results related to the extension and spectrum of PS J1934.5+1845.
