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.

Plasma lensing models show that outer and inner caustics plus arclet brightness patterns in pulsar scintillation can constrain substructure column density gradients, sizes, and amplitudes.
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
A masked and initialized variant of Kaiser-Squires weak lensing inversion recovers cluster mass maps with residuals below 0.02 sigma in unmasked nonlinear regions on simulated data without shape noise.
Gravitational lensing is recast as an optical phenomenon governed by effective refractive index, yielding closed-form deflection angles and Einstein radii for modified gravity models including deep-MOND, Yukawa, and power-law f(R).

Self-Lensing Signals in Binary Systems Containing White Dwarfs with Neutron star or Stellar-mass Black hole Companions
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
