Detection of a new GeV source in the outer region of the Coma cluster: a
signature of external accretion shock ?
Detection of a new GeV source in the outer region of the Coma cluster: a
signature of external accretion shock ?
The supersonic flow motions associated with infall of baryonic gas toward sheets and filaments, as well as cluster mergers, produces large-scale shock waves. The shocks associated with galaxy clusters can be classified mainly into two categories: internal shocks appear in the hot intracluster medium within the viral radius, and external …
