Preto, Miguel, Amaro-Seoane, Pau
We present, for the first time, a clear $N$-body realization of the {\it strong mass segregation} solution for the stellar distribution around a massive black hole. We compare our $N$-body results...

On post-Newtonian orbits and the Galactic-center stars (2009)
Preto, Miguel, Saha, Prasenjit
Stars near the Galactic center reach a few percent of light speed during pericenter passage, which makes post-Newtonian effects potentially detectable. We formulate the orbit equations in Hamiltonian...
Binary Black Hole Merger in Galactic Nuclei: Post-Newtonian Simulations (2008)
Berentzen, Ingo, Preto, Miguel, Berczik, Peter, Merritt, David, Spurzem, Rainer
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 first N-body...

Merger of Massive Black Holes using N-Body Simulations with Post-Newtonian Corrections (2008)
Preto, Miguel, Berentzen, Ingo, Berczik, Peter, Merritt, David, Spurzem, Rainer
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 the black hole...

N-body studies of galactic nuclei with massive black holes (2007)
Massive black holes (MBHs) are ubiquituous in galactic nuclei. The collisional dynamics of these $systems is studied with high resolution, direct $N$-body simulations and its results are...

N-Body Growth of a Bahcall-Wolf Cusp Around a Black Hole (2004)
Preto, Miguel, Merritt, David, Spurzem, Rainer
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 system. Our N-body...
Scattering of Stars by Transient Spiral Waves (2002)
Sellwood, J. A., Preto, Miguel
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: for a wave of ~20%...
A class of symplectic integrators with adaptive timestep for separable Hamiltonian systems (1999)
Preto, Miguel, Tremaine, Scott
Symplectic integration algorithms are well-suited for long-term integrations of Hamiltonian systems because they preserve the geometric structure of the Hamiltonian flow. However, this desirable...
