Constraining Black Hole Populations in Globular Clusters using Microlensing: Application to Omega Centauri
John Zaris, Doğa Veske, Johan Samsing +3
We estimate the rate of gravitational microlensing events of cluster stars due to black holes (BHs) in the globular cluster NGC 5139 (). Theory and observations both indicate…
Probing the Survival of Planetary Systems in Globular Clusters with Tidal Disruption Events
Kyle Kremer, Daniel J. D'Orazio, Johan Samsing +2
Among the growing list of confirmed exoplanets, the number of planets identified in dense star clusters remains sparse. Previous analyses have suggested this may be due in part to…
Analytic computation of the secular effects of encounters on a binary: third-order perturbation, octupole, and post-Newtonian terms; steady-state distribution
Adrian S. Hamers, Johan Samsing
Dense stellar systems such as globular clusters are believed to harbor merging binary black holes (BHs). The evolution of such binaries is driven by interactions with other stars,…
Single-single gravitational-wave captures in globular clusters: Eccentric deci-Hertz sources observable by DECIGO and Tian-Qin
Johan Samsing, Daniel J. D'Orazio, Kyle Kremer +2
We study the formation rate of binary black hole mergers formed through gravitational-wave emission between unbound, single black holes in globular clusters. While the formation of…
The Effect of Distant Encounters on Black Hole Binaries in Globular Clusters: Systematic Increase of In-cluster Mergers in the LISA band
Johan Samsing, Adrian S. Hamers, Jacob G. Tyles
We present the first systematic study on how distant weak interactions impact the dynamical evolution of merging binary black holes (BBHs) in dense stellar clusters. Recent studies…
Analytic computation of the secular effects of encounters on a binary: features arising from second-order perturbation theory
Adrian S. Hamers, Johan Samsing
Binary-single interactions play a crucial role in the evolution of dense stellar systems such as globular clusters. In addition, they are believed to drive black hole (BH) binary m…
Probing the Black Hole Merger History in Clusters using Stellar Tidal Disruptions
Johan Samsing, Tejaswi Venumadhav, Liang Dai +5
The dynamical assembly of binary black holes (BBHs) in dense star clusters (SCs) is one of the most promising pathways for producing observable gravitational wave (GW) sources, how…
