Abstract
Galaxy clusters (GCs) are the largest and most massive gravitationally bound objects in the large-scale structure of the Universe. Due to keV temperatures of virialized gas in the intracluster medium (ICM) and presence of cosmic rays (CRs), galaxy clusters are effective sources of thermal X-ray radiation and non-thermal leptonic (synchrotron) radio emission. Galaxy clusters are also store-rooms for hadronic CRs, but non-thermal hadronic gamma-ray emission (mainly, due to pp collisions and subsequent pion decay) from galaxy clusters has not been detected yet. In this work we present the simulation of the expected non-thermal hadronic gamma-ray and neutrino emission from the dominant part of Hercules cluster (A2151) and estimated a perspective of detection of this emission by existing (Fermi-LAT, LHASSO, IceCube) and planned (CTA, IceCube-Gen2) ground-based and space-based detectors.
