Investigating the region of 3C 397 in High Energy Gamma rays
  We investigate the supernova remnant (SNR) 3C 397 and its neighboring pulsar
PSR J1906+0722 in high energy gamma rays by using nearly six years of archival
data of {\it Large Area Telescope} on board {\it Fermi Gamma Ray Space
Telescope} (Fermi-LAT). The off-pulse analysis of gamma-ray flux from the
location of PSR J1906+0722 reveals an excess emission which is found to be very
close to the radio location of 3C 397. Here, we present the preliminary results
of this gamma-ray analysis of 3C 397 and PSR J1906+0722.
