TL;DR
This study analyzes six years of Fermi-LAT gamma-ray data to explore high-energy emissions from supernova remnant 3C 397 and nearby pulsar PSR J1906+0722, revealing excess emission near 3C 397.
Contribution
First gamma-ray analysis of 3C 397 and PSR J1906+0722 using archival Fermi-LAT data, identifying excess emission near the supernova remnant.
Findings
Detected gamma-ray excess near 3C 397
Off-pulse analysis reveals emission close to supernova remnant
Preliminary results suggest potential gamma-ray association
Abstract
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.
