This study aims to derive model-independent constraints on the Hubble parameter using stellar ages from passively evolving early-type galaxies in the SDSS. By fitting Lick index absorption lines, the authors provide a value of H0 = 70.0+4.1−7.6 km s−1 Mpc−1, which is competitive with existing measurements. The research highlights an unexpected oscillating pattern in critical indices with respect to redshift, suggesting potential issues in data reduction processes.
