Early formation of supermassive black holes via dark matter self-interactions [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 The existence of supermassive black holes at high redshifts (z∼7) is difficult to accommodate in standard astrophysical scenarios. It has been shown that dark matter models with a subdominant self-interacting component are able to produce early seeds for

Can Supermassive Black Holes alter Cold Dark Matter cusps through accretion? [PDF]
Mon.Not.Roy.Astron.Soc. 339 (2003) 949, 2002 We present some simple models to determine whether or not the accretion of cold dark matter by supermassive black holes is astrophysically important. Contrary to some claims in the literature, we show that supermassive black holes cannot significantly alter a power law density cusp via accretion, whether during mergers or in the steady state.

Evolution of supermassive black holes [PDF]
, 2011 The cosmological evolution of supermassive black holes (SMBHs) seems to be intimately linked to their host galaxies. Active galactic nuclei (AGN) can be probed by deep X-ray surveys. We review results from large X-ray selected samples including first results from the XMM-Newton COSMOS survey.

The supermassive black hole of Fornax A★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 The radio galaxy Fornax A (NGC 1316) is a prominent merger remnant in the outskirts of the Fornax cluster. Its giant radio lobes suggest the presence of a powerful AGN and thus a central supermassive black hole (SMBH). We present high-resolution adaptive optics assisted integral-field data of Fornax A, taken with SINFONI at the Very Large Telescope in ...

Dynamics of galaxy cores and supermassive black holes [PDF]
Rept.Prog.Phys. D69 (2006) 2513-2579, 2006 Recent work on the dynamical evolution of galactic nuclei containing supermassive black holes is reviewed. Topics include galaxy structural properties; collisionless and collisional equilibria; loss-cone dynamics; and dynamics of binary and multiple supermassive black holes.

Wandering Supermassive Black Holes in Milky-Way-mass Halos [PDF]
, 2018 We present a self-consistent prediction from a large-scale cosmological simulation for the population of “wandering” supermassive black holes (SMBHs) of mass greater than 106 M ⊙ on long-lived, kpc-scale orbits within Milky Way (MW)-mass galaxies.

Ram-pressure feeding of supermassive black holes [PDF]
Nature, 2017 When a supermassive black hole at the centre of a galaxy accretes matter, it gives rise to a highly energetic phenomenon: an active galactic nucleus. Numerous physical processes have been proposed to account for the funnelling of gas towards the galactic

The Astrophysical Journal, 2023 The early evolution of the quasar luminosity function (QLF) and black hole mass function (BHMF) encodes key information on the physics determining the radiative and accretion processes of supermassive black holes (BHs) in high- z quasars.
