The IMPETUS project: Using ABACUS for the high performance computation of radiative tables for accretion onto a galaxy black hole

Abstract

We present the intensive calculations of digital tables for the radiative terms that appear in the energy and momentum equations used to simulate the accretion onto supermassive black holes (SMBHs) at the centers of galaxies. Cooling and heating rates are presented, calculated with a Spectral Energy Distribution constructed from: an accretion disk plus an X-ray power-law and an accretion disk plus a Corona. The electronic structures of atoms, the photoionization cross-sections, and the recombination rates are treated in great detail. With the recent discovery of outflows originating at sub-parsec scales, these tables may provide a useful tool for modeling gas accretion processes onto a SMBH.
