In the early Universe, while galaxies were still forming, black holes as massive as a billion solar masses powered quasars. Supermassive black holes are found at the centres of most galaxies today, where their masses are related to the velocity dispersions of stars in their host galaxies and hence to the mass of the central bulge of the galaxy. This suggests a link between the growth of the black holes and their host galaxies, which has indeed been assumed for a number of years. But the origin… Expand
Evolution of Supermassive Black Holes
Supermassive black holes (SMBHs) are nowadays believed to reside in most local galaxies, and the available data show an empirical correlation between bulge luminosity or stellar velocity dispersionExpand
The suppression of star formation by powerful active galactic nuclei
Submillimetre and X-rays observations show that rapid star formation was common in the host galaxies of AGN when the Universe was 2–6 billion years old, but that the most vigorous star formation is not observed around black holes above an X-ray luminosity of 1044 ergs per second. Expand
Formation and Evolution of Supermassive Black Holes
The correlation between the mass of supermassive black holes in galaxy nuclei and the mass of the galaxy spheroids or bulges (or more precisely their central velocity dispersion), suggests a commonExpand
A unified model for AGN feedback in cosmological simulations of structure formation
We discuss a numerical model for black hole growth and its associated feedback processes that for the first time allows cosmological simulations of structure formation to self-consistently follow theExpand
Supermassive black holes as the regulators of star formation in central galaxies
We present a relationship between the black hole mass, stellar mass, and star formation rate of a diverse group of 91 galaxies with dynamically-measured black hole masses. For our sample of galaxiesExpand
The Role of Black Holes in Galaxy Mergers
In the paper “Black Holes in Galaxy Mergers: The Formation of Red Elliptical Galaxies”[1], researchers use a new model and show that growing black holes release a blast of energy that fundamentallyExpand
Tracing black hole and galaxy co-evolution in the Romulus simulations
We study the link between supermassive black hole growth and the stellar mass assembly of their host galaxies in the state-of-the-art Romulus suite of simulations. The cosmological simulationsExpand
The formation of galaxies hosting z ̃ 6 quasars
We investigate the formation and properties of galaxies hosting z∼ 6 quasars in the gigaparsec scale cosmological hydrodynamical simulation MassiveBlack, which includes a self-consistent model forExpand
Determining the Properties and Evolution of Red Galaxies from the Quasar Luminosity Function
We study the link between quasars and the red galaxy population using a model for self-regulated growth of supermassive black holes in gas-rich galaxy mergers. Using a model for quasar evolutionExpand
The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations andExpand


Black holes in galaxy mergers: The Formation of red elliptical galaxies
We use hydrodynamical simulations to study the color transformations induced by star formation and active galactic nuclei (AGNs) during major mergers of spiral galaxies. Our modeling accounts forExpand
A unified model for the evolution of galaxies and quasars
We incorporate a simple scheme for the growth of supermassive black holes into semi-analytic models that follow the formation and evolution of galaxies in a cold dark matter-dominated Universe. WeExpand

Recent X-ray observations of intense high-speed outflows in quasars suggest that supercritical accretion on to the central black hole may have an important effect on a host galaxy. I revisit someExpand
The mass density of massive black holes observed locally is consistent with the hard X-ray background provided that most of the radiation produced during their growth was absorbed by surrounding gas.Expand
Self-regulated Growth of Supermassive Black Holes in Galaxies as the Origin of the Optical and X-Ray Luminosity Functions of Quasars
We postulate that supermassive black holes grow in the centers of galaxies until they unbind the galactic gas that feeds them. We show that the corresponding self-regulation condition yields aExpand
A Physical Model for the Coevolution of QSOs and Their Spheroidal Hosts
We present a physically motivated model for the early coevolution of massive spheroidal galaxies and active nuclei at their centers. Within dark matter halos, forming at the rate predicted by theExpand
The Assembly and Merging History of Supermassive Black Holes in Hierarchical Models of Galaxy Formation
We assess models for the assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical buildup far up in the dark halo merger tree. Motivated by the recentExpand

We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with aExpand
Formation of a spiral galaxy in a major merger
