Stellar Escape from Globular Clusters. I. Escape Mechanisms and Properties at Ejection
Newlin C. Weatherford, Fulya Kıroğlu, Giacomo Fragione +3
The theory of stellar escape from globular clusters (GCs) dates back nearly a century, especially the gradual evaporation of GCs via two-body relaxation coupled with external tides…
Growing Black Holes through Successive Mergers in Galactic Nuclei: I. Methods and First Results
Dany Atallah, Alessandro A. Trani, Kyle Kremer +4
We present a novel, few-body computational framework designed to shed light on the likelihood of forming intermediate-mass (IM) and supermassive (SM) black holes (BHs) in nuclear s…
Partial Tidal Disruption of Main-Sequence Stars by Intermediate-Mass Black Holes
Fulya Kıroğlu, James C. Lombardi, Kyle Kremer +3
We study close encounters of a middle-age main-sequence star (modeled using MESA) with massive black holes through hydrodynamic simulations, and explore in particula…
Intermediate-mass Black Holes on the Run from Young Star Clusters
Elena González Prieto, Kyle Kremer, Giacomo Fragione +4
The existence of black holes (BHs) with masses in the range between stellar remnants and supermassive BHs has only recently become unambiguously established. GW190521, a gravitatio…
Millisecond Pulsars in Dense Star Clusters: Evolution, Scaling Relations, and the Galactic-Center Gamma-ray Excess
Claire S. Ye, Giacomo Fragione
The number of millisecond pulsars (MSPs) observed in Milky Way globular clusters has increased explosively in recent years, but the underlying population is still uncertain due to…
Implication of spin constraints by the Event Horizon Telescope on stellar orbits in the Galactic Center
Giacomo Fragione, Abraham Loeb
The center of the Milky Way hosts the closest supermassive black hole, SgrA. Decades of near-infrared observations of our Galactic Center have shown the presence of a small pop…
