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.
New simulations show that cross-correlating gravitational wave background anisotropies with galaxy distributions can enable discovery at angular scales of 4-6 degrees with next-generation observatories.
Statistical combination of sub-threshold post-merger signals from 50-70 BNS events can constrain the maximum mass of hot neutron stars to 11-20% fractional uncertainty, potentially translating to 12-21% on the cold TOV mass.
92% of 91 LIGO black hole mergers favor non-zero V_GW, constraining bound remnants to at most 8% and finding no cosmological handedness preference with average near zero.
Semi-analytical models show AGN disks produce repeated BBH mergers with a high-mass tail beyond the pair-instability gap, more efficiently at low viscosity, with spin and mass-ratio signatures that can match events like GW190521.
LILA can detect IMBH binaries at redshifts 20-30, IMRIs, and provide months-to-years early warnings with high-SNR events for gravity tests.
A targeted gravitational-wave search modifies the GstLAL likelihood ratio with a sky localization prior from EM triggers, showing improved detection efficiency in injection studies while controlling false alarms.
Simulations show LIGO-A# constrains the peak redshift of binary black hole merger rate (tracing star formation) to ±0.1 in one year, improving to ±0.02 with next-generation detectors.
Cosmic Explorer and Einstein Telescope will detect w-modes from spinning neutron stars with good signal-to-noise ratio.
Calculations showing that rapidly spinning black holes permit stable orbits close enough to the horizon for extreme time dilation matching Interstellar, with suggested astrophysical uses.

Sub-threshold post-merger gravitational waves can constrain the hot nuclear equation of state
Statistical combination of sub-threshold post-merger signals from 50-70 BNS events can constrain the maximum mass of hot neutron stars to 11-20% fractional uncertainty, potentially translating to 12-21% on the cold TOV mass.
