Scolnic et al. have released a preprint detailing an updated measurement of the Hubble constant (H0) at 73.22±2.06 km/s/Mpc, derived from the Tip of the Red Giant Branch (TRGB) method. Their study utilizes an optimized unsupervised algorithm, Comparative Analysis of TRGBs (CATs), to standardize measurements across multiple fields, addressing challenges in replicating TRGB data. The analysis incorporates a larger sample of Type Ia supernova hosts and corrects for discrepancies in previous studies, which contributed to a significant difference in H0 values. The research highlights an empirical correlation found in the GHOSTS halo survey, enhancing the accuracy of TRGB measurements. This new determination is notably higher than earlier TRGB estimates, indicating a shift in understanding the universe's expansion rate.
