Intermediate Mass Black Hole Formation in compact Young Massive Star Clusters
Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem +6
Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carr…
Step-size effect in the time-transformed leapfrog integrator on elliptic and hyperbolic orbits
Long Wang, Keigo Nitadori
A drift-kick-drift (DKD) type leapfrog symplectic integrator applied for a time-transformed separable Hamiltonian (or time-transformed symplectic integrator; TSI) has been known to…
PeTar: a high-performance N-body code for modeling massive collisional stellar systems
Long Wang, Masaki Iwasawa, Keigo Nitadori +1
The numerical simulations of massive collisional stellar systems, such as globular clusters (GCs), are very time-consuming. Until now, only a few realistic million-body simulations…
Very high redshift quasars and the rapid emergence of super-massive black holes
Pavel Kroupa, Ladislav Subr, Tereza Jerabkova +1
The observation of quasars at very high redshift such as Poniuaena is a challenge for models of super-massive black hole (SMBH) formation. This work presents a study of SMBH format…
