Direct sampling under a uniform-in-dL prior raises P(H0>120) from 0.017 to 0.159 for GW170817; post-hoc reweighting recovers only 0.041 because a low-dL mode is undersampled.

Discovery of a gravitationally lensed Type II supernova at z=1.37 with magnification ≳100×, confirmed via multi-telescope spectra and imaging.
Mixing electromagnetic radiation with dark radiation between BBN and recombination dilutes the baryon-to-entropy ratio, tightening the allowed total extra radiation to at most ~25% more than dark-radiation-only scenarios.

BAGPIPES fitting of 9289 massive quiescent galaxies shows most SFHs rise gradually then quench in 1-2 Gyr, with faster quenching at z>1 and slower at z<1, interpreted as multiple AGN feedback and gas-supply mechanisms.
Bilby-antiglitch jointly models astrophysical signals and quasi-physical glitches to recover true source properties from simulated gravitational wave data contaminated by loud non-Gaussian transients.
Joint NICER+IXPE pulse-profile modeling of SRGA J144459.2-604207 favors large neutron-star mass and radius with two independent hotspots but shows strong sensitivity to joint-analysis methodology.
Pulsar radio emission beams from the two poles are generally dissimilar in azimuth width and often radius, based on rotating vector model fits to polarization data from eight double-pole interpulse pulsars.
WASP-96b shows super-solar metallicity of 2-6x stellar, roughly stellar C/O, tentative SO2 consistent with photochemistry, and an optical slope from scattering aerosols, supporting core-accretion formation beyond the water snowline.
Ca-rich gap transients and 91bg-like SNe occupy similar massive quiescent host parameter space with peak delay times around 10^4 Myr, unlike normal Type Ia (~10^3 Myr) and Type II (~10 Myr) SNe.
