Relativistic protons in the Coma galaxy cluster: first gamma-ray constraints ever on turbulent reacceleration
Relativistic protons in the Coma galaxy cluster: first gamma-ray constraints ever on turbulent reacceleration
The Fermi-LAT collaboration recently published deep upper limits to the gamma-ray emission of the Coma cluster, a cluster that hosts the prototype of giant radio halos. In this paper we extend previous studies and use a formalism that combines particle reacceleration by turbulence and the generation of secondary particles in …
