Abstract

The local universe is dominated by quiescent galaxies with little or no ongoing star formation. Once star formation has been shut down in a possible quasar phase, energy feedback in the form of outflows from a supermassive black hole (SMBH) accreting at a low rate is one of the leading candidates for heating up or removing gas accreted afterwards. In this work we performed hydrodynamic simulations of radiatively inefficient accretion flows around supermassive black holes and investigate the generation of outflows by the accretion flow. We found that hot accretion flows can produce powerful subrelativistic winds that carry considerable amounts of energy away and they can provide feedback inside the host galaxy. (AU)
