New evidence for links between SNOBs and galactic gamma-ray sources
Abstract
The most recent COS-B data show that SNOBs (i.e., supernova remnants physically linked with OB associations) are likely to be a class of gamma-ray sources. The relativistic electrons present in the SNR generate gamma rays via the inverse Compton effect on the photon field of the associated H II region, and via bremsstrahlung on the surrounding dense medium. While the contribution of the first process is shown to be generally small, bremsstrahlung can account for the observed gamma-ray flux.
