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.
Efficient mass transfer in binaries naturally limits the mass of the first-born black hole and produces a sharp drop above 45 solar masses that mimics the pair-instability gap.
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.
No evidence for core-collapse formed low-spin IMBHs in GWTC-4, with 90% upper limit on merger rate of 0.077 Gpc^{-3} yr^{-1}, low-spin BH mass truncation at 65 solar masses consistent with pair-instability gap lower edge, and high-spin IMBHs from hierarchical mergers.
Non-detection of kilonova from S250206dm excludes AT 2017gfo-like events and disfavors NS-BH mergers with mass ratio Q >= 3.2, reaching GW-comparable precision on the mass gap candidate.
GPU-accelerated gwcosmo enables 1000x faster dark-siren cosmological analyses for large GW catalogs.
No sub-solar mass binary merger candidates found in LIGO data from May 2023 to January 2024, yielding merger rate upper limits of 110-10000 Gpc^{-3}yr^{-1} and constraints on primordial black hole dark matter fractions.
Improved quantitative detection of SASI in supernovae is reported using cWB XP on real LIGO O3/O4 data, with high identification probabilities at 1-10 kpc distances via ROC curves.
