GeV light curves of young supernova remnants
Abstract
Observational data from the Fermi Gamma-ray Space Telescope are analyzed with a goal in mind to look for variations in gamma-ray flux from young shell-like supernova remnants. Uniform methodological approach is adopted for all SNRs considered. G1.9+0.3 and Kepler SNRs are not detected. The light curves of Cas~A and Tycho SNRs are compatible with the steady GeV flux during the recent ten years, as also X-ray and radio fluxes. Less confident results on SN1006 and SN1987A are discussed.
