Primordial Origins of Supermassive Black Holes [PDF]

open access: yes, 2019
At the center of the Milky Way sits a supermassive black hole named Sagittarius A*1, which is over a million times the mass of our sun. Other galaxy centers host similar black holes which are up to thousands of times larger than even Sagittarius A*. Some

Tidal disruption flares from stars on eccentric orbits

open access: yesEPJ 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.

Supermassive black holes: Coevolution (or not) of black holes and host galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractSupermassive black holes (BHs) have been found in 75 galaxies by observing spatially resolved dynamics. The Hubble Space Telescope (HST) revolutionized BH work by advancing the subject from its ‘proof of concept’ phase into quantitative studies of BH demographics.

Bayesian Black Hole Photogrammetry

open access: yesThe Astrophysical Journal
We propose an analytic dual-cone accretion model for horizon-scale images of the cores of low-luminosity active galactic nuclei, including those observed by the Event Horizon Telescope (EHT).

High-energy signatures of binary supermassive black holes

open access: yesEPJ Web of Conferences, 2013
Some active galactic nuclei are supposed to harbor binary systems of supermassive black holes. They are an attractive target for gravitational wave experiments.

Dynamics Around Supermassive Black Holes: Extreme-mass-ratio Inspirals as Gravitational-wave Sources

open access: yesThe Astrophysical Journal
Supermassive black holes and their surrounding dense stellar environments nourish a variety of astrophysical phenomena. We focus on the distribution of stellar-mass black holes around the supermassive black hole and the consequent formation of extreme ...
