High-energy emission from the galaxy cluster Abell 3376

Abstract

Cluster of galaxies are extremely powerful X-ray sources, with luminosities L(X) 10^43-45 erg/s. Some galaxy clusters also show radio emission. The radio luminosity is interpreted as synchrotron radiation produced by relativistic particles accelerated at strong large-scale shocks present in clusters. The interaction of relativistic particles with photons and matter produce high-energy emission. We investigate the particular case of the cluster of galaxies Abell 3376. The resulting spectral energy distribution obtained from the most relevant non-thermal processes indicates that this cluster might be detected at gamma-rays by future planned Cherenkov arrays.
