The Acceleration of Relativistic Particles in a Cluster of Accreting Black Holes Pacholczyk, A. G. ; Stepinski, T. F. Abstract An accreting cluster of black holes in an active galactic nucleus is a natural site for a system of shock structures with a hierarchy of sizes, corresponding to the distribution of masses in the cluster. Accreted gas containing some magnetic fields and supersonically falling onto the core forms shocks on the outside of each hole and these shocks are capable of accelerating relativistic particles. The energies reached in a single shock are size rather than acceleration time limited and are proportional to the mass of the hole with a proportionality constant being a function of the position of the hole within a cluster and the model of the cluster and the shock formation. These energies are adequate to explain the observed properties of synchrotron and inverse-Compton radiation from these objects. The resulting energy spectrum of particles in the cluster in zeroth approximation has the form of a doubly broken power law with indices of 2 and 3 on both extremes of the energy domain respectively, bridged by an index of ~2.5.
