Missed opportunities: GRB 211211A and the case for continual gravitational-wave coverage with a single observatory
Nikhil Sarin, Paul D. Lasky, Rowina S. Nathan
Gamma-ray burst GRB 211211A may have been the result of a neutron star merger at Mpc. However, none of the LIGO-Virgo detectors were operating at the time. We show tha…
Magnetic dynamo caused by axions in neutron stars
Filippo Anzuini, José A. Pons, Antonio Gómez-Bañón +3
The coupling between axions and photons modifies Maxwell's equations, introducing a dynamo term in the magnetic induction equation. In neutron stars, for critical values of the axi…
A Rosetta Stone for eccentric gravitational waveform models
Alan M. Knee, Isobel M. Romero-Shaw, Paul D. Lasky +2
Orbital eccentricity is a key signature of dynamical binary black hole formation. The gravitational waves from a coalescing binary contain information about its orbital eccentricit…
Generating transient noise artifacts in gravitational-wave detector data with generative adversarial networks
Jade Powell, Ling Sun, Katinka Gereb +2
Transient noise glitches in gravitational-wave detector data limit the sensitivity of searches and contaminate detected signals. In this Paper, we show how glitches can be simulate…
Four eccentric mergers increase the evidence that LIGO--Virgo--KAGRA's binary black holes form dynamically
Isobel M. Romero-Shaw, Paul D. Lasky, Eric Thrane
The growing population of compact binary mergers detected with gravitational waves contains multiple events that are challenging to explain through isolated binary evolution. Such…
Gravitational-wave inference for eccentric binaries: the argument of periapsis
Teagan A. Clarke, Isobel M. Romero-Shaw, Paul D. Lasky +1
Gravitational waves from binary black hole mergers have allowed us to directly observe stellar-mass black hole binaries for the first time, and therefore explore their formation ch…
