Measuring the parameters of supermassive black holes from space

open access: yes, 2005
To describe black hole in astrophysics typically astronomers use Newtonian approaches for gravitational field because usually one analyzes processes acting far enough (in Schwarz- schild radius units) from black hole horizons.

Supermassive black holes with stellar companions

open access: yesAIP Conference Proceedings, 1994
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 ...

Constraints on Alternatives to Supermassive Black Holes

open access: yes, 2020
Observations of the centers of galaxies continue to evolve, and it is useful to take a fresh look at the constraints that exist on alternatives to supermassive black holes at their centers.

Supermassive gravitinos and giant primordial black holes

open access: yes, 2020
We argue that the stable (color singlet) supermassive gravitinos proposed in our previous work can serve as seeds for giant primordial black holes. These seeds are hypothesized to start out as tightly bound states of fractionally charged gravitinos in ...

Dance of Two Supermassive Binary Black Holes

open access: yes, 2018
Black holes exist in a various range of masses ranging from stellar mass (~ 10 Solar Mass) to Supermassive black holes (SMBHs, million to billion Solar Mass).

Galactic Collisions: The Growth and Merger of Supermassive Black Holes

open access: yes, 2017
The discovery of gravitational waves from two merging black holes at cosmological distance motivates the study of the galactic environments hosting coalescing black holes.

Capture Rates of Compact Objects by Supermassive Black Holes

open access: yes, 2006
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.

Multiple supermassive black holes in galactic bulges

open access: yes, 2002
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.
