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…
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…
N-Body Growth of a Bahcall-Wolf Cusp Around a Black Hole
Miguel Preto, David Merritt, Rainer Spurzem
We present a clear N-body realization of the growth of a Bahcall-Wolf f ~ E^0.25 (rho ~ 1/r^1.75) density cusp around a massive object ("black hole") at the center of a stellar sys…
Scattering of Stars by Transient Spiral Waves
J. A. Sellwood, Miguel Preto
Transient spiral waves of moderate amplitude cause substantial changes to the angular momenta of many stars in a galaxy disk. Stars near to corotation are affected most strongly: f…
A class of symplectic integrators with adaptive timestep for separable Hamiltonian systems
Miguel Preto, Scott Tremaine
Symplectic integration algorithms are well-suited for long-term integrations of Hamiltonian systems because they preserve the geometric structure of the Hamiltonian flow. However,…
