Supernova Remnants Interacting With Molecular Clouds: New Observations With The Fermi-lat
Abstract
Supernova remnant (SNR) shocks are expected to be sites of cosmic rays acceleration, and clouds of dense material can provide effective targets for production of gamma-rays from pion decay. There exists a population of SNRs which show evidence of interaction with molecular clouds, and we report on a study of the gamma-ray emission coincident with these supernova remnants using data from the Large Area Telescope on board the Fermi Gamma-ray Space Telescope. Detailed spatial and spectral analysis of the Fermi LAT observations in the regions of these SNRs provides constraints on the origin of the gamma-ray emission.
