[GA331] Gamma-ray Emission from Supernova Remnants

Description

Supernova Remnants (SNRs) have been a favored source of Galactic cosmic rays (CRs) for many decades. This talk will highlight information gleaned from studies of known SNRs using gamma-rays, including from the First Fermi Supernova Remnant Catalog. Current observations suggest that known SNRs could contribute the entire source of directly measured CRs, but do not yet require it. Other observations paint a more complex picture than thus far used for these estimates, indicating the necessity of improved acceleration models and estimators of environment, such as nearby molecular clouds, and distance.
