Gamma-ray lines in advection dominated accretion flows
Abstract
Gamma-ray line fluxes from the deexcitation of nuclei in accretion disks around galactic black holes are evaluated in the framework of the ADAF model. It is argued that previous evaluations have overestimated those fluxes and that, even under very optimistic assumptions, only the Sgr A ∗ black hole in the Galactic Center could be marginally detectable by INTEGRAL.
