Wide Jets or Low Rates: Reconciling Short GRB and Gravitational-Wave Neutron Star Merger Rates
Keerthi Kunnumkai, Antonella Palmese, Brendan O'Connor +2
Gravitational wave (GW) and short Gamma Ray Burst (sGRB) observations provide us with complementary views of compact object mergers. The paucity of binary neutron star merger (BNS)…
The maximum mass ratio of hierarchical binary black hole mergers may cause the - correlation
Aditya Vijaykumar, Amanda M. Farah, Maya Fishbach
Regardless of their initial spins, the merger of two roughly equal mass black holes (BHs) produces a remnant BH of dimensionless spin . Such remnants can merge with other BHs…
The steep redshift evolution of the hierarchical binary black hole merger rate may cause the - correlation
Amanda M. Farah, Aditya Vijaykumar, Maya Fishbach
There is growing evidence from gravitational-wave observations that some merging black holes are created from previous mergers. Using the prediction that these hierarchically merge…
Evidence of the pair instability gap from black hole masses
Hui Tong, Maya Fishbach, Eric Thrane +13
Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…
Gravitational lensing rarely produces high-mass outliers to the compact binary population
Amanda M. Farah, Jose María Ezquiaga, Maya Fishbach +1
All gravitational-wave signals are inevitably gravitationally lensed by intervening matter as they propagate through the Universe. When a gravitational-wave signal is magnified, it…
Bridging the Gap: Categorizing Gravitational-Wave Events at the Transition Between Neutron Stars and Black Holes
Amanda M. Farah, Maya Fishbach, Reed Essick +2
We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars and black holes. We analyze all gravitati…
Probing Extremal Gravitational-Wave Events with Coarse-Grained Likelihoods
Reed Essick, Amanda Farah, Shanika Galaudage +4
As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pai…
Counting on Short Gamma-Ray Bursts: Gravitational-Wave Constraints of Jet Geometry
Amanda Farah, Reed Essick, Zoheyr Doctor +2
The detection of GW170817 in gravitational waves and gamma rays revealed that short gamma-ray bursts are associated with the merger of neutron-stars. Gamma rays are thought to resu…
