Detection of Gamma Rays from a Starburst Galaxy
Detection of Gamma Rays from a Starburst Galaxy
Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the remnants of which are thought to accelerate energetic cosmic rays up to energies of ~ 10^15 eV. We report the detection of gamma rays -- tracers of such cosmic rays -- from the starburst galaxy NGC …
