Capture Rates of Compact Objects by Supermassive Black Holes [PDF]
8 pages, 3 figures; accepted for publication in PRDCapture rates of compact objects were calculated by using a recent solution of the Fokker-Planck equation in energy-space, including two-body resonant effects.

A Comparison of the X-Ray Polarimetric Properties of Stellar and Supermassive Black Holes
X-ray polarization provides a new way to probe accretion geometry in black hole systems. If the accretion geometry of black holes is similar regardless of mass, we should expect the same to be true of their polarization properties.

Multiple supermassive black holes in galactic bulges [PDF]
We study the number and interaction rates of supermassive black holes in galactic bulges as predicted by hierarchical models of galaxy formation in which the spheroidal components of galaxies are formed by mergers.

Tidal disruption flares from stars on eccentric orbits
We study tidal disruption and subsequent mass fallback for stars approaching supermassive black holes on bound orbits, by performing three dimensional Smoothed Particle Hydrodynamics simulations with a pseudo-Newtonian potential.

Supermassive black holes with stellar companions
Low‐mass stars in close orbits around supermassive black holes in active galactic nuclei (AGN) may provide an important signature for testing the existence of supermassive black holes. Here we discuss how such systems can form by being ‘‘ground down’’ by their interaction with an AGN accretion disk and discuss the peculiarities of such binaries with ...

The Black Hole Spin Controversy [PDF]
Astrophysical black holes are the simplest possible objects. They are completely described by only two parameters in general relativity, their mass and the specific angular momentum, spin.

The contribution of supermassive black holes in stripped nuclei to the supermassive black hole population of UCDs and galaxy clusters [PDF]
We use the hydrodynamic EAGLE simulation to predict the numbers and masses of supermassive black holes in remnant nuclei of disrupted galaxies (stripped nuclei) and compare these to confirmed measurements of black holes in observed ultra-compact dwarf ...

A semi-empirical model to constrain the growth of supermassive black holes [PDF]
openThe presence of super massive black holes (SMBHs) at the center of galaxies has been proved by the most recent observations. The mass of these SMBHs is found to correlate with a number of properties of the host galaxies and such relations have been ...
