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.

PI-ResNet, a time-domain Siamese 1D ResNet with SE modules, identifies strongly lensed GW candidate pairs from whitened strain data with reported accuracies of 93.8-95.6% on simulated ET noise and 78-84% on LIGO noise.
Mock catalogs GW-LMC-Space predict 0-131 lensed MBHB events for 4-year LISA (prob. up to 0.3%) and 0-44 for 1-year DECIGO (prob. ~0.15%), with signal overlap noted as common.
GWTC-5.0 is a data release documenting over 300 gravitational-wave events from compact binary mergers observed through early 2025.
