The Dynamical Evolution of Stellar Black Holes in Globular Clusters

Meagan Morscher, Bharath Pattabiraman, Carl Rodriguez +2

Our current understanding of the stellar initial mass function and massive star evolution suggests that young globular clusters may have formed hundreds to thousands of stellar-mas…

Retention of Stellar-Mass Black Holes in Globular Clusters

Meagan Morscher, Stefan Umbreit, Will M. Farr +1

Globular clusters should be born with significant numbers of stellar-mass black holes (BHs). It has been thought for two decades that very few of these BHs could be retained throug…

Constraining Intermediate-Mass Black Holes in Globular Clusters

Stefan Umbreit, Frederic A. Rasio

Decades after the first predictions of intermediate-mass black holes (IMBHs) in globular clusters (GCs) there is still no unambiguous observational evidence for their existence. Th…

Understanding the Dynamical State of Globular Clusters: Core-Collapsed vs Non Core-Collapsed

Sourav Chatterjee, Stefan Umbreit, John M. Fregeau +1

We study the dynamical evolution of globular clusters using our Hénon-type Monte Carlo code for stellar dynamics including all relevant physics such as two-body relaxation, single…

A Parallel Monte Carlo Code for Simulating Collisional N-body Systems

Bharath Pattabiraman, Stefan Umbreit, Wei-Keng Liao +4

We present a new parallel code for computing the dynamical evolution of collisional N-body systems with up to N~10^7 particles. Our code is based on the the Henon Monte Carlo metho…

Quantifying the Universality of the Stellar Initial Mass Function in Old Star Clusters

Nathan Leigh, Stefan Umbreit, Alison Sills +4

We present a new technique to quantify cluster-to-cluster variations in the observed present-day stellar mass functions of a large sample of star clusters. Our method quantifies th…
