Binary Black Hole Merger in Galactic Nuclei: Post-Newtonian Simulations
Ingo Berentzen, Miguel Preto, Peter Berczik +2
This paper studies the formation and evolution of binary supermassive black holes (SMBHs) in rotating galactic nuclei, focusing on the role of stellar dynamics. We present the firs…
Merger of Massive Black Holes using N-Body Simulations with Post-Newtonian Corrections
Miguel Preto, Ingo Berentzen, Peter Berczik +2
We present preliminary results from self-consistent, high resolution direct {\it N}-body simulations of massive black hole binaries in mergers of galactic nuclei. The dynamics of t…
High resolution in z-direction: The simulation of disc-bulge-halo galaxies using the particle-mesh code SUPERBOX
R. Bien, A. Just, P. Berczik +1
SUPERBOX is known as a very efficient particle-mesh code with highly-resolving sub-grids. Nevertheless, the height of a typical galactic disc is small compared to the size of the w…
Anatomy of the Bar Instability in Cuspy Dark Matter Halos
John Dubinski, Ingo Berentzen, Isaac Shlosman
We examine the bar instability in galactic models with an exponential disk and a cuspy dark matter (DM) halo with a Navarro-Frenk-White (NFW) cosmological density profile. We const…
Post-Newtonian simulations of super-massive black hole binaries in galactic nuclei
I. Berentzen, M. Preto, P. Berczik +2
We present some preliminary results from recent numerical simulations that model the evolution of super-massive black hole (SMBH) binaries in galactic nuclei. Including the post-Ne…
Bars in Cuspy Dark Halos
John Dubinski, Ingo Berentzen, Isaac Shlosman
We examine the bar instability in models with an exponential disk and a cuspy NFW-like dark matter (DM) halo inspired by cosmological simulations. Bar evolution is studied as a fun…
Gas Feedback on Stellar Bar Evolution
Ingo Berentzen, Isaac Shlosman, Inma Martinez-Valpuesta +1
We analyze evolution of live disk-halo systems in the presence of various gas fractions, f_gas less than 8% in the disk. We addressed the issue of angular momentum (J) transfer fro…
Growing Live Disks Within Cosmologically Assembling Asymmetric Halos: Washing Out the Halo Prolateness
Ingo Berentzen, Isaac Shlosman
We study the growth of galactic disks in live triaxial DM halos. The halos have been assembled through constrained realizations method and evolved from the linear regime using cosm…
Stellar Bar Evolution in Cuspy and Flat-Cored Triaxial CDM Halos
Ingo Berentzen, Isaac Shlosman, Shardha Jogee
We analyze the evolution of stellar bars in galactic disks in mildly triaxial flat-core and cuspy CDM halos. We use tailored simulations of rigid and live halos which include the f…
The regeneration of stellar bars by tidal interactions. Numerical simulations of fly-by encounters
I. Berentzen, E. Athanassoula, C. H. Heller +1
We study the regeneration of stellar bars triggered by a tidal interaction, using numerical simulations of either purely stellar or stellar+gas disc galaxies. We find that interact…
Numerical simulations of interacting gas-rich barred galaxies. Vertical impact of small companions
I. Berentzen, E. Athanassoula, C. H. Heller +1
We investigate the dynamical effects of an interaction between an initially barred galaxy and a small spherical companion using an N-body/SPH algorithm. In the models described her…
Gas-driven evolution of stellar orbits in barred galaxies
I. Berentzen, C. H. Heller, I. Shlosman +1
We carry out a detailed orbit analysis of gravitational potentials selected at different times from an evolving self-consistent model galaxy consisting of a two-component disk (sta…
