GW250114 data confirm the remnant is consistent with a Kerr black hole and bound the dominant quadrupolar mode frequency to within a few percent of the GR prediction, with constraints tighter than prior multi-event catalogs.

GWTC-4 data analysis yields a pair-instability mass gap lower edge at 44.3^{+5.9}_{-3.5} M_⊙, an S-factor of 268^{+195}_{-116} keV b for ^{12}C(α,γ)^{16}O, and two populations supporting both direct formation and hierarchical mergers.
Introduces catability metric rooted in nonlinear squeezing for detecting cat-like features in quantum superpositions, shown numerically robust to loss.
Thermal aberrations induce low-pass frequency dynamics for quadratic wavefront mismatches and high-pass dynamics for higher-order aberrations, degrading squeezed states differently in current versus future gravitational wave detectors.
No sub-solar-mass compact-binary mergers were found in LIGO O4a data, giving 90% merger-rate upper limits of 110-10000 Gpc^-3 yr^-1 and weak new dark-matter constraints.
The dissipative quantum limit is extended from stationary to general non-stationary quantum sensors.
GWTC-5.0 is a data release documenting over 300 gravitational-wave events from compact binary mergers observed through early 2025.
LIGO-Virgo-KAGRA releases calibrated strain time series, noise-subtraction channels, and GWOSC v5.0 analysis products covering April 2024 to January 2025.
