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…
Prospects for Detecting Fast Radio Bursts in Globular Clusters of Nearby Galaxies
Kyle Kremer, Dongzi Li, Wenbin Lu +2
The recent detection of a repeating fast radio burst (FRB) in an old globular cluster in M81 challenges traditional FRB formation mechanisms based on magnetic activity in young neu…
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…
Hyper-Eddington Black Hole Growth in Star-Forming Molecular Clouds and Galactic Nuclei: Can It Happen?
Yanlong Shi, Kyle Kremer, Michael Y. Grudić +2
Formation of supermassive black holes (BHs) remains a theoretical challenge. In many models, especially beginning from stellar relic "seeds," this requires sustained super-Eddingto…
Radio detection of an elusive millisecond pulsar in the Globular Cluster NGC 6397
Lei Zhang, Alessandro Ridolfi, Harsha Blumer +32
We report the discovery of a new 5.78 ms-period millisecond pulsar (MSP), PSR J1740-5340B (NGC 6397B), in an eclipsing binary system discovered with the Parkes radio telescope (now…
Probing the efficiency of tidal synchronization in outspiralling double white dwarf binaries with LISA
Sylvia Biscoveanu, Kyle Kremer, Eric Thrane
Compact-object binaries including a white dwarf component are unique among gravitational-wave sources because their evolution is governed not just by general relativity and tides,…
Formation of Low-mass Black Holes and Single Millisecond Pulsars in Globular Clusters
Kyle Kremer, Claire S. Ye, Fulya Kıroğlu +3
Close encounters between neutron stars and main-sequence stars occur in globular clusters and may lead to various outcomes. Here we study encounters resulting in tidal disruption o…
Astrophysics with the Laser Interferometer Space Antenna
Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda +156
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many…
Stellar graveyards: Clustering of compact objects in globular clusters NGC 3201 and NGC 6397
Eduardo Vitral, Kyle Kremer, Mattia Libralato +2
We analyse Gaia EDR3 and re-calibrated HST proper motion data from the core-collapsed and non core-collapsed globular clusters NGC 6397 and NGC 3201, respectively, with the Bayesia…
Hydrodynamics of Collisions and Close Encounters between Stellar Black Holes and Main-sequence Stars
Kyle Kremer, James C. Lombardi, Wenbin Lu +2
Recent analyses have shown that close encounters between stars and stellar black holes occur frequently in dense star clusters. Depending upon the distance at closest approach, the…
