Relativistic outflows (mainly observed in the radio) are a characteristic feature of both Galactic stellar mass black holes and supermassive black holes (SMBHs). Simultaneous radio and X-ray observations of Galactic sources have shown that the outflow is strong at low accretion rates, but it weakens dramatically or disappears completely at high accretion rates, manifesting structural changes in the accretion flow. It is reasonable to assume that SMBHs follow the same trend. For low luminosity… 
Correlations between supermassive black holes, hot atmospheres, and the total masses of early-type galaxies
We present a study of relations between the masses of the central supermassive black holes (SMBHs) and the atmospheric gas temperatures and luminosities measured within a range of radii between Re
Host galaxies of high-redshift quasars: SMBH growth and feedback
The properties of quasar-host galaxies might be determined by the growth and feedback of their supermassive black holes (SMBHs, 108−10 M⊙). We investigate such connection with a suite of
The Interplay of Kinetic and Radiative Feedback in Galaxy Clusters
Recent observations provide evidence that some cool-core clusters host quasars in their brightest cluster galaxies (BCGs). Motivated by these findings, we use 3D radiation-hydrodynamic simulations
Correlations between supermassive black holes and hot gas atmospheres in IllustrisTNG and X-ray observations
Recent X-ray observations have revealed remarkable correlations between the masses of central supermassive black holes (SMBHs) and the X-ray properties of the hot atmospheres permeating their host
Ionized Gas Outflows in Low-excitation Radio Galaxies Are Radiation Driven
Low-excitation radio galaxies (LERGs) are weakly accreting active galactic nuclei (AGNs) believed to be fueled by radiatively inefficient accretion processes. Despite this, recent works have shown
The connection between star formation and supermassive black hole activity in the local Universe
We present a study of the active galactic nucleus (AGN) activity in the local Universe (I < 0.33) and its correlation with the host galaxy properties, derived from an Sloan Digital Sky Survey (SDSS
Self-regulated growth of supermassive black holes by a dual jet-heating active galactic nucleus feedback mechanism: methods, tests and implications for cosmological simulations
We develop a new sub-grid model for the growth of supermassive Black Holes (BHs) and their associated Active Galactic Nuclei (AGN) feedback in hydrodynamical cosmological simulations. Assuming that
The rise of active galactic nuclei in the galaxy evolution and assembly semi-analytic model
We present a new implementation of the GAlaxy Evolution and Assembly (GAEA) semi-analytic model, that features an improved modelling of the process of cold gas accretion onto supermassive black hole
Quenching star formation with quasar outflows launched by trapped IR radiation
We present cosmological radiation-hydrodynamic simulations, performed with the code Ramses-RT, of radiatively-driven outflows in a massive quasar host halo at $z = 6$. Our simulations include both
Black hole mass of central galaxies and cluster mass correlation in cosmological hydro-dynamical simulations
Context. The correlations between the properties of the brightest cluster galaxy (BCG) and the mass of its central super-massive black hole (SMBH) have been extensively studied from a theoretical and
