Supernova Remnants: Galactic Cosmic Ray Accelerators

Supernova remnants (SNRs) and pulsar wind nebulae (PWNe) are considered to be the most promising candidates for the acceleration of particles to cosmic ray (CR) energies ($\leq10^{15}$,eV). This paper reports the investigation into candidate CR accelerators and their respective counterparts. Very high energy (VHE, E$>$50,GeV) $\gamma$-ray emission is discovered by Fermi-LAT on the western edge of the supernova remnant known as SNR-G344.7-0.1, which is reported in the 2FHL catalog. This source, 2FHL-J1703.4-4145, likely has a TeV counterpart, HESS-J1702-420. The observed gamma-ray emission is a possible byproduct of the interaction between the SNR shock-wave and a molecular gas cloud. We present a summary of supernova remnants as Galactic accelerators and discuss examples. X-ray data reduction and analysis is performed on available X-ray data of SNR-G344.7-0.1 to understand the region overlapping with the 2FHL counterpart.
