Dark Sirens Yield Intermediate Hubble Constant Measurement
7.2
Relevance Score
A team using LIGO/Virgo/KAGRA data combined seventeen well-localized gravitational-wave "dark sirens" with deep galaxy surveys and machine learning to estimate the Hubble constant at 69.9 km/s/Mpc. The independent measurement sits between cosmic-microwave-background values (~67 km/s/Mpc) and local supernova estimates (~73 km/s/Mpc), offering a distinct observational probe that may help constrain the ongoing H0 tension.
Scoring Rationale
Independent LIGO/Virgo/KAGRA dark-siren measurement increases confidence in intermediate H0 but remaining uncertainties prevent definitive resolution.
