4-OGC: Catalog of Gravitational Waves from Compact Binary Mergers [PDF]

open access: yesAstrophysical Journal, 2021
We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star (BNS), binary black hole (BBH), and neutron star–black hole (NSBH) mergers.

The Dynamics of Binary Neutron Star Mergers and GW170817 [PDF]

open access: yes, 2020
With the first observation of a binary neutron star merger through gravitational waves and light GW170817, compact binary mergers have now taken the center stage in nuclear astrophysics.

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs [PDF]

open access: yes, 2018
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of the Advanced gravitational-wave detector network. During the first

AGN as potential factories for eccentric black hole mergers [PDF]

open access: yesNature, 2020
There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity1,2. In addition, the masses of the component black holes exceeded the limit predicted by stellar evolution3. The large masses can be explained by successive

Black Hole Genealogy: Identifying Hierarchical Mergers with Gravitational Waves [PDF]

open access: yesAstrophysical Journal, 2020
In dense stellar environments, the merger products of binary black hole mergers may undergo additional mergers. These hierarchical mergers are naturally expected to have higher masses than the first generation of black holes made from stars.

Binary Black Hole Mergers in the First Advanced LIGO Observing Run [PDF]

open access: yes, 2016
The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers.

Eccentric Black Hole Mergers in Active Galactic Nuclei [PDF]

open access: yesAstrophysical Journal, 2020
The astrophysical origin of gravitational wave transients is a timely open question in the wake of discoveries by the Laser Interferometer Gravitational-Wave Observatory (LIGO)/Virgo. In active galactic nuclei (AGNs), binaries form and evolve efficiently

Binary Neutron Star Mergers: Mass Ejection, Electromagnetic Counterparts, and Nucleosynthesis [PDF]

open access: yesAstrophysical Journal, 2018
We present a systematic numerical relativity study of the mass ejection and the associated electromagnetic transients and nucleosynthesis from binary neutron star (NS) mergers.

New binary black hole mergers in the second observing run of Advanced LIGO and Advanced Virgo [PDF]

open access: yesPhysical Review D, 2019
We report the detection of new binary black hole merger events in the publicly available data from the second observing run of advanced LIGO and advanced Virgo (O2). The mergers were discovered using the new search pipeline described in Venumadhav et al.

Mass-gap Mergers in Active Galactic Nuclei [PDF]

open access: yesAstrophysical Journal, 2020
The recently discovered gravitational wave sources GW190521 and GW190814 have shown evidence of BH mergers with masses and spins outside of the range expected from isolated stellar evolution.
