ABSTRACT: Hot accretion disk coronae may account for substantial X-ray flux in AGN. We present preliminary results from a novel coronal emission model which builds upon the knowledge we have of solar-stellar coronae. The model considers a population of accelerated electrons (such as produced at the onset of a flare) injected at the top of an accretion disk magnetic loop. The inverse Compton and bremsstrahlung emission for the electron population is computed and compared with AGN X-ray observations. The constraints on model parameters are discussed.
