The centers of elliptical galaxies host supermassive black holes that - through feedback resulting from the accretion process - are believed to significantly affect their hot interstellar medium. The evolution of this hot gas together with that of the nuclear emission during the whole galaxies lifetime has been studied with the aid of high-resolution hydrodynamical simulations, with cooling and heating functions including photoionization plus Compton process, and specific for an average AGN spectral energy distribution.

Abstract
The centers of elliptical galaxies host supermassive black holes that - through feedback resulting from the accretion process - are believed to significantly affect their hot interstellar medium. The evolution of this hot gas together with that of the nuclear emission during the whole galaxies lifetime has been studied with the aid of high-resolution hydrodynamical simulations, with cooling and heating functions including photoionization plus Compton process, and specific for an average AGN spectral energy distribution.File in questo prodotto:
