Mass-gap Mergers in Active Galactic Nuclei
Hiromichi Tagawa, Bence Kocsis, Zoltan Haiman +3
The recently discovered gravitational wave sources GW190521 and GW190814 have shown evidence of BH mergers with masses and spins that could be outside of the range expected from is…
Gravitational Waves as a Probe of Globular Cluster Formation and Evolution
Isobel M. Romero-Shaw, Kyle Kremer, Paul D. Lasky +2
Globular clusters are considered to be likely breeding grounds for compact binary mergers. In this paper, we demonstrate how the gravitational-wave signals produced by compact obje…
Search for Black Hole Merger Families
Doğa Veske, Andrew G. Sullivan, Zsuzsa Márka +5
The origin, environment, and evolution of stellar-mass black hole binaries are still a mystery. One of the proposed binary formation mechanisms is manifest in dynamical interaction…
Eccentric Black Hole Mergers in Active Galactic Nuclei
Hiromichi Tagawa, Bence Kocsis, Zoltan Haiman +3
The astrophysical origin of gravitational wave (GW) transients is a timely open question in the wake of discoveries by LIGO/Virgo. In active galactic nuclei (AGNs), binaries form a…
AGN as Potential Factories for Eccentric Black Hole Mergers
J. Samsing, I. Bartos, D. J. D'Orazio +6
There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity. In addition, the component black holes' masses exceeded the limit predicted by st…
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…
Populating the Black Hole Mass Gaps In Stellar Clusters: General Relations and Upper Limits
Johan Samsing, Kenta Hotokezaka
Theory and observations suggest that single-star evolution is not able to produce black holes (BHs) with masses in the range and above , referred t…
Binary-binary scattering in the secular limit
Adrian S. Hamers, Johan Samsing
Binary-binary interactions are important in a number of astrophysical contexts including dense stellar systems such as globular clusters. Although less frequent than binary-single…
Have hierarchical three-body mergers been detected by LIGO/Virgo?
Doğa Veske, Zsuzsa Márka, Andrew Sullivan +4
One of the proposed channels of binary black hole mergers involves dynamical interactions of three black holes. In such scenarios, it is possible that all three black holes merge i…
