Resumen:
We present results of a study of non-thermal, time-dependent particle injection in a corona around
an accreting black hole. We model the spectral energy distribution of high-energy flares in this
scenario. We consider particle interactions with magnetic, photon and matter fields in the black
hole magnetosphere. Transport equations are solved for all species of particles and the electromagnetic output is predicted. Photon annihilation is taken into account for the case of systems
with early-type donor stars.
