Title: The Investigation of Non-Thermal Hard X-ray Emission in Coma Cluster
Proposal ID: 0120134
Subject category: Extragalactic Object
Principal investigator: Vikhlinin
Institute: Space Research Institute (IKI)
Abstract
We propose a 500 ksec INTEGRAL observation of Coma, the cluster of galaxies with a powerful radio halo,
detction of the hard X-ray emission from the cluster at $E\ge100$ keV will aloow us to distinguish
between
different mechanisms of generation of the hard X-ray emission (inverse Compton vs. suprathermal
bremsstrahlung), and to derive the energy densities of the magnetic field and relativistic particles in the
intracluster medium.
