Constraints on the X-Ray and Very-high-energy Gamma-Ray Flux from Supernova Remnant W44

Constraints on the X-Ray and Very-high-energy Gamma-Ray Flux from Supernova Remnant W44

Observations of GeV gamma-ray emission from the well-studied mixed-morphology supernova remnant (SNR) W44 by Fermi-Large Area Telescope and AGILE imply that it is a site of significant cosmic-ray acceleration. The spectral energy distribution (SED) derived from the GeV data suggests that the gamma-r...
