Simulating tidal disruption events in nuclear star clusters
Philip Cho, Kai Wu, Francesco Flammini Dotti +5
Context. Nuclear star clusters (NSCs) and supermassive black holes (SMBHs) often coexist at the centers of galaxies, engaging in complex dynamical interactions that influence SMBH…
Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: An Multi-mass Direct N-body Model
Shuo Li, Shiyan Zhong, Peter Berczik +3
By using direct N-body numerical simulations, we model the dynamical co-evolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to…
Extreme-mass-ratio burst detection with TianQin
Hui-Min Fan, Shiyan Zhong, Zheng-Cheng Liang +3
The capture of compact objects by massive black holes in galaxies or dwarf galaxies will generate short gravitational wave signals, called extreme-mass-ratio bursts (EMRBs), before…
Revisit the rate of tidal disruption events: the role of the partial tidal disruption event
Shiyan Zhong, Shuo Li, Peter Berczik +1
Tidal disruption of stars in dense nuclear star clusters containing supermassive central black holes (SMBH) is modeled by high-accuracy direct N-body simulation. Stars getting too…
Exploring the origin of stars on bound and unbound orbits causing tidal disruption events
Shiyan Zhong, Kimitake Hayasaki, Shuo Li +2
Tidal disruption events (TDEs) provide a clue to the properties of a central supermassive black hole (SMBH) and an accretion disk around it, and to the stellar density and velocity…
Classification of Tidal Disruption Events Based on Stellar Orbital Properties
Kimitake Hayasaki, Shiyan Zhong, Shuo Li +2
We study the rates of tidal disruption of stars by intermediate-mass to supermassive black holes on bound to unbound orbits by using high-accuracy direct N-body experiments. The ap…
Supermassive Black Holes in Galactic Nuclei with Tidal Disruption of Stars: Paper II - Axisymmetric Nuclei
Shiyan Zhong, Peter Berczik, Rainer Spurzem
Tidal Disruption of stars by supermassive central black holes from dense rotating star clusters is modelled by high-accuracy direct N-body simulation. As in a previous paper on sph…
Efficient Scheme for Active Particle Selection in N-body Simulations
Shiyan Zhong
We propose an efficient method for active particle selection, working with Hermite Individual Time Steps (HITS) scheme in direct N-body simulation code GRAPE. For a simulation w…
SMBH in Galactic Nuclei with Tidal Disruption of Stars
Shiyan Zhong, Peter Berczik, Rainer Spurzem
Tidal Disruption of stars by super massive central black holes from dense star clusters is modeled by high-accuracy direct -body simulation. The time evolution of the stellar ti…
Up to 700k GPU cores, Kepler, and the Exascale future for simulations of star clusters around black holes
P. Berczik, R. Spurzem, L. Wang +9
We present direct astrophysical N-body simulations with up to a few million bodies using our parallel MPI/CUDA code on large GPU clusters in China, Ukraine and Germany, with differ…
