Black holes grow by accreting matter from their surroundings. However, angular momentum provides an efficient natural barrier to accretion and so only the lowest angular momentum material will be available to feed the black holes. The standard subgrid model for black hole accretion in galaxy formation simulations - based on the Bondi-Hoyle method - does not account for the angular momentum of accreting material, and so it is not clear how representative the black hole accretion rate estimated…

Accretion disc particle accretion in major merger simulations
A recent approach to simulating localized feedback from active galactic nuclei by Power et al. (2011) uses an accretion disc particle to represent both the black hole and its accretion disc. We have
Galactic nuclei evolution with spinning black holes: method and implementation
Supermassive black holes at the centre of galactic nuclei mostly grow in mass through gas accretion over cosmic time. This process also modifies the angular momentum (or spin) of black holes, both in
The impact of angular momentum on black hole accretion rates in simulations of galaxy formation
Feedback from energy liberated by gas accretion onto black holes (BHs) is an attractive mechanism to explain the exponential cut-off at the massive end of the galaxy stellar mass function (SMF).
Simulations of supermassive black hole growth in high-redshift disc galaxies
Observations suggest that a large fraction of black hole growth occurs in normal star-forming disk galaxies. Here we describe simulations of black hole accretion in isolated disk galaxies with
Black hole feeding and feedback: the physics inside the "subgrid"
Black holes (BHs) are believed to be a key ingredient of galaxy formation. However, the galaxy-BH interplay is challenging to study due to the large dynamical range and complex physics involved. As a
Seeding black holes in cosmological simulations
We present a new model for the formation of black holes in cosmological simulations, motivated by the first star formation. Black holes form from high density peaks of primordial gas, and grow via
Accretion on to black holes formed by direct collapse
One possible scenario for the formation of massive black holes (BHs) in the early Universe is from the direct collapse of primordial gas in atomic-cooling dark matter haloes in which the gas is
The growth of supermassive black holes fed by accretion disks
Context. Supermassive black holes are probably present in the centre of the majority of the galaxies. There is consensus that these exotic objects are formed by the growth of seeds either by mass
An analytic model of angular momentum transport by gravitational torques: from galaxies to massive black holes
We present analytic calculations of angular momentum transport and gas inflow in galaxies, from scales of ∼ kpc to deep inside the potential of a central massive black hole (BH). We compare these
The closest black holes
Starting from the assumption that there is a large population (> 10^8) of isolated, stellar-mass black holes (IBH) distributed throughout our galaxy, we consider the detectable signatures of


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.
Selfgravity and QSO disks
It is well known that the outer parts of QSO accretion disks are prone to selfgravity if heated solely by orbital dissipation. Such disks might be expected to form stars rather than accrete onto the
Self-gravity and quasi-stellar object discs
The outer parts of standard steady-state accretion discs around quasi-stellar objects (QSOs) are prone to self-gravity, and they might be expected to fragment into stars rather than feed the central
Cosmological simulations of the growth of supermassive black holes and feedback from active galactic nuclei: method and tests
We present a method that self-consistently tracks the growth of supermassive black holes (BHs) and the feedback from active galactic nuclei (AGN) in cosmological, hydrodynamical simulations. Our
Modelling feedback from stars and black holes in galaxy mergers
We describe techniques for incorporating feedback from star formation and black hole (BH) accretion into simulations of isolated and merging galaxies. At present, the details of these processes
Radiative feedback from quasars and the growth of massive black holes in stellar spheroids
We discuss the importance of feedback via photoionization and Compton heating on the co-evolution of massive black holes (MBHs) at the centre of spheroidal galaxies, and their stellar and gaseous
Energy input from quasars regulates the growth and activity of black holes and their host galaxies
Simulations that simultaneously follow star formation and the growth of black holes during galaxy–galaxy collisions find that, in addition to generating a burst of star formation, a merger leads to strong inflows that feed gas to the supermassive black hole and thereby power the quasar.
Variable accretion and emission from the stellar winds in the Galactic Centre
Numerical simulations of stellar wind dynamics in the central parsec of the Galactic Centre are presented, studying in particular the accretion of gas on to Sgr A ∗ , the supermassive black hole, and the possibility of constraining the total mass-loss rate of the ‘slow-wind stars’ using near infrared observations of gas in thecentral few arcseconds is shown.
Black Hole Outflows
I show that Eddington accretion episodes in active galactic nuclei (AGN) are likely to produce winds with velocities υ ~ 0.1c and ionization parameters up to ξ ~ 10 4 (cgs), implying the presence of

We investigate the relationship between black hole mass and host galaxy properties for active galaxies with the lowest black hole masses currently known in galaxy nuclei. HST imaging confirms that
