Nuclear coups: dynamics of black holes in galaxy mergers
Sandor Van Wassenhove, Pedro R. Capelo, Marta Volonteri +4
We study the dynamical evolution of supermassive black holes (BHs) in merging galaxies on scales of hundreds of kpc to 10 pc, to identify the physical processes that aid or hinder…
The Relative Role of Galaxy Mergers and Cosmic Flows in Feeding Black Holes
Jillian Bellovary, Alyson Brooks, Marta Volonteri +3
Using a set of zoomed-in cosmological simulations of high-redshift progenitors of massive galaxies, we isolate and trace the history of gas that is accreted by central supermassive…
Black Holes in the Early Universe
Marta Volonteri, Jillian Bellovary
The existence of massive black holes was postulated in the sixties, when the first quasars were discovered. In the late nineties their reality was proven beyond doubt, in the Milky…
Observability of Dual Active Galactic Nuclei in Merging Galaxies
Sandor Van Wassenhove, Marta Volonteri, Lucio Mayer +3
Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are the products of billions of years of galaxy mergers, but also…
SMBH Formation via Gas Accretion in Nuclear Stellar Clusters
Melvyn B. Davies, M. Coleman Miller, Jillian M. Bellovary
Black holes exceeding a billion solar masses have been detected at redshifts greater than six. The rapid formation of these objects may suggest a massive early seed or a period of…
The First Massive Black Hole Seeds and Their Hosts
Jillian Bellovary, Marta Volonteri, Fabio Governato +3
We investigate the formation of the first massive black holes in high redshift galaxies, with the goal of providing insights to which galaxies do or do not host massive black holes…
Wandering Black Holes in Bright Disk Galaxy Halos
Jillian Bellovary, Fabio Governato, Tom Quinn +3
We perform SPH+N-body cosmological simulations of massive disk galaxies, including a formalism for black hole seed formation and growth, and find that satellite galaxies containing…
Growing Massive Black Hole Pairs in Minor Mergers of Disk Galaxies
S. Callegari, S. Kazantzidis, L. Mayer +4
We perform a suite of high-resolution smoothed particle hydrodynamics simulations to investigate the orbital decay and mass evolution of massive black hole (MBH) pairs down to scal…
The nature of HI absorbers in GRB afterglows: clues from hydrodynamic simulations
Andrew Pontzen, Alis Deason, Fabio Governato +6
In recent work, we have shown that it is possible to link quantitatively many aspects of damped Lyman alpha (DLA) absorbers in the spectra of quasars to high resolution simulations…
