Echoes of the Universe: Unveiling Gravitational Wave Lensing

20.12.2025 by qfx

The inference of lensing parameters for gravitational wave event GW231123, represented by filled contours, aligns with simulations of similarly massive binary systems lacking lensing effects (unfilled contours), suggesting a robust assessment even without observable magnification.

A new deep-learning framework is helping scientists identify and analyze subtle distortions in gravitational wave signals caused by the bending of spacetime, as demonstrated by a re-analysis of the GW231123 event.
