No definitive lensing is detected in GW231123, though a potential microlensing feature with modulation amplitude up to 0.8 at 95% confidence is noted, limited by large waveform systematics in short signals.
A recursive sum-over-round-trips model enables fast time-domain simulation of optical cavities with arbitrary time-varying boundaries and non-linear resonance-crossing dynamics.
BBH-Genesis applied to GWTC-4 finds strongest support for a two-channel model of binary black hole populations with possible mild evidence for an AGN-related third channel.
Bayesian modeling with informed priors reduces uncertainties in neutron-star crust shear properties, predicting torsional mode frequencies of 20-50 Hz compatible with observations.
Describes the methods for producing the fifth gravitational-wave transient catalog (GWTC-5.0) from O4b data of LIGO, Virgo and KAGRA.
LIGO-Virgo-KAGRA releases calibrated strain time series, noise-subtraction channels, and GWOSC v5.0 analysis products covering April 2024 to January 2025.
