LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
Binary black hole scattering with generic spins
Adam Clark, Geraint Pratten, Patricia Schmidt
In this Letter, we confront high-order post-Minkowskian (PM) predictions for generic-spin black-hole scattering with numerical-relativity (NR) simulations for the first time, targe…
Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object
Elise M. Sänger, Soumen Roy, Michalis Agathos +16
On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Fast neural network surrogate for multimodal effective-one-body gravitational waveforms from generically precessing compact binaries
Christopher Whittall, Geraint Pratten
Gravitational waveform templates are a key ingredient for the detection and characterization of gravitational waves emitted by compact binary mergers in the universe. These templat…
Post-Newtonian inspiral waveform model for eccentric precessing binaries with higher-order modes and matter effects
Gonzalo Morras, Geraint Pratten, Patricia Schmidt +1
We introduce pyEFPEHM, a post-Newtonian (PN) inspiral waveform model for eccentric and spin-precessing compact binaries that includes higher-order modes and matter effects. Accurat…
