Explaining the Orbits of the Galactic Center S-Stars
David Merritt, Alessia Gualandris, Seppo Mikkola
The young stars near the supermassive black hole at the galactic center follow orbits that are nearly random in orientation and that have an approximately thermal distribution of e…
Dynamical evolution of the young stars in the Galactic center
Hagai. B. Perets, Alessia Gualandris, David Merritt +1
Recent observations of the Galactic center revealed a nuclear disk of young OB stars near the massive black hole (MBH), in addition to many similar outlying stars with higher eccen…
A parallel gravitational N-body kernel
Simon Portegies Zwart, Steve McMillan, Derek Groen +3
We describe source code level parallelization for the {\tt kira} direct gravitational -body integrator, the workhorse of the {\tt starlab} production environment for simulating…
Dynamics around supermassive black holes
Alessia Gualandris, David Merritt
The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass…
Ejection of Supermassive Black Holes from Galaxy Cores
Alessia Gualandris, David Merritt
[Abridged] Recent numerical relativity simulations have shown that the emission of gravitational waves during the merger of two supermassive black holes (SMBHs) delivers a kick to…
On the onset of runaway stellar collisions in dense star clusters I. Dynamics of the first collision
E. Gaburov, A. Gualandris, S. Portegies Zwart
We study the circumstances under which first collisions occur in young and dense star clusters. The initial conditions for our direct -body simulations are chosen such that the…
