No rungs attached: A distance-ladder free determination of the Hubble constant through type II supernova spectral modelling
Christian Vogl, Stefan Taubenberger, Géza Csörnyei +10
The ongoing discrepancy in the Hubble constant () estimates obtained through local distance ladder methods and early universe observations poses a significant challenge to the…
