Fast Optical Transients from Stellar-Mass Black Hole Tidal Disruption Events in Young Star Clusters
Kyle Kremer, Wenbin Lu, Anthony L. Piro +3
Observational evidence suggests that the majority of stars may have been born in stellar clusters or associations. Within these dense environments, dynamical interactions lead to h…
Gravitational Wave observatories may be able to detect hyperbolic encounters of Black Holes
Sajal Mukherjee, Sanjit Mitra, Sourav Chatterjee
Gravitational Wave (GW) astronomy promises to observe different kinds of astrophysical sources. Here we explore the possibility of detection of GWs from hyperbolic interactions of…
Black Hole Mergers from Hierarchical Triples in Dense Star Clusters
Miguel A. S. Martinez, Giacomo Fragione, Kyle Kremer +8
Hierarchical triples are expected to be produced by the frequent binary-mediated interactions in the cores of globular clusters. In some of these triples, the tertiary companion ca…
Demographics of triple systems in dense star clusters
Giacomo Fragione, Miguel A. S. Martinez, Kyle Kremer +6
Depending on the stellar type, more than \% and of stars in the field have at least one and two stellar companions, respectively. Hierarchical systems can be a…
Populating the upper black hole mass gap through stellar collisions in young star clusters
Kyle Kremer, Mario Spera, Devin Becker +6
Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function above for BHs formed through single star evolution, arising from (…
GW190412 as a Third-Generation Black Hole Merger from a Super Star Cluster
Carl L. Rodriguez, Kyle Kremer, Michael Y. Grudić +8
We explore the possibility that GW190412, a binary black hole merger with a non-equal-mass ratio and significantly spinning primary, was formed through repeated black hole mergers…
