Reconstructing the origin of black hole mergers using sparse astrophysical models
V. Gayathri, Giuliano Iorio, Hiromichi Tagawa +8
The astrophysical origin of binary black hole mergers discovered by LIGO and Virgo remains uncertain. Efforts to reconstruct the processes that lead to mergers typically rely on ei…
Low-latency gravitational wave alert products and their performance at the time of the fourth LIGO-Virgo-KAGRA observing run
Sushant Sharma Chaudhary, Andrew Toivonen, Gaurav Waratkar +50
Multi-messenger searches for BNS and NSBH mergers are currently one of the most exciting areas of astronomy. The search for joint electromagnetic and neutrino counterparts to GWs h…
A Common Origin for Low Mass Ratio Events Observed by LIGO and Virgo in the First Half of the Third Observing Run
Mohammadtaher Safarzadeh, Daniel Wysocki
In its third observing run, the LIGO/Virgo collaboration has announced a potential neutron star-black hole (NSBH) merger candidate, GW190426_152155. Together with GW190814, these t…
Black Hole Coagulation: Modeling Hierarchical Mergers in Black Hole Populations
Zoheyr Doctor, Daniel Wysocki, Richard O'Shaughnessy +2
Data from the LIGO and Virgo detectors has confirmed that stellar-mass black holes can merge within a Hubble time, leaving behind massive remnant black holes. In some astrophysical…
Monte-Carlo simulations of black hole mergers in AGN disks: Low mergers and predictions for LIGO
B. McKernan, K. E. S. Ford, R. O'Shaughnessy +1
Accretion disks around supermassive black holes are promising sites for stellar mass black hole mergers detectable with LIGO. Here we present the results of Monte-Carlo simulations…
Spin orientations of merging black holes formed from the evolution of stellar binaries
Davide Gerosa, Emanuele Berti, Richard O'Shaughnessy +4
We study the expected spin misalignments of merging binary black holes (BHs) formed in isolation by combining state-of-the-art population-synthesis models with efficient post-Newto…
Explaining LIGO's observations via isolated binary evolution with natal kicks
D. Wysocki, D. Gerosa, R. O'Shaughnessy +5
We compare binary evolution models with different assumptions about black-hole natal kicks to the first gravitational-wave observations performed by the LIGO detectors. Our compari…
Inferences about supernova physics from gravitational-wave measurements: GW151226 spin misalignment as an indicator of strong black-hole natal kicks
Richard O'Shaughnessy, Davide Gerosa, Daniel Wysocki
The inferred parameters of the binary black hole GW151226 are consistent with nonzero spin for the most massive black hole, misaligned from the binary's orbital angular momentum. I…
