A Population of Short-Period Variable Quasars from PTF as Supermassive Black Hole Binary Candidates [PDF]

, 2016
Supermassive black hole binaries (SMBHBs) at sub-parsec separations should be common in galactic nuclei, as a result of frequent galaxy mergers. Hydrodynamical simulations of circum-binary discs predict strong periodic modulation of the mass accretion ...

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.

Tidal disruption flares from stars on eccentric orbits

EPJ Web of Conferences, 2012
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.

Selection bias in dynamically measured supermassive black hole samples: its consequences and the quest for the most fundamental relation [PDF]

, 2016
We compare the set of local galaxies having dynamically measured black holes with a large, unbiased sample of galaxies extracted from the Sloan Digital Sky Survey.

Signatures of primordial black holes as seeds of supermassive black holes [PDF]

Journal of Cosmology and Astroparticle Physics, 2018
It is broadly accepted that Supermassive Black Holes (SMBHs) are located in the centers of most massive galaxies, although there is still no convincing scenario for the origin of their massive seeds. It has been suggested that primordial black holes (PBHs) of masses $\gtrsim 10^{2} M_\odot$ may provide such seeds, which would grow to become SMBHs.

On the High-Energy Neutrino Emission from Active Galactic Nuclei

Universe, 2018
We review observational aspects of the active galactic nuclei and their jets in connection with the detection of high-energy neutrinos by the Antarctic IceCube Neutrino Observatory.

The persistent shadow of the supermassive black hole of M 87

Astronomy & Astrophysics
In April 2019, the Event Horizon Telescope (EHT) Collaboration reported the first-ever event-horizon-scale images of a black hole, resolving the central compact radio source in the giant elliptical galaxy M 87. These images reveal a ring with a southerly

Modeling Polarized Emission from Black Hole Jets: Application to M87 Core Jet

Galaxies, 2017
We combine three-dimensional general-relativistic numerical models of hot, magnetized Advection Dominated Accretion Flows around a supermassive black hole and the corresponding outflows from them with a general relativistic polarized radiative transfer ...
