DOI: 10.1038/s41550-017-0313-z

Abstract: How do you build a (distance) ladder from the closest stars to the far-away supernovae and all the way back to the last scattering surface of the Universe? Jeremy Mould summarizes some of the highlights… read more here.

DOI: 10.1093/mnras/stad1590

Abstract: The local distance ladder estimate of the Hubble constant (H0) is important in cosmology, given the recent tension with the early universe inference. We estimate H0 from the Type Ia supernova (SN Ia) distance ladder,… read more here.

DOI: 10.1093/mnras/staf122

Abstract: We measure the current expansion rate of the Universe, Hubble’s constant H0, by calibrating the absolute magnitudes of supernovae to distances measured by Baryon Acoustic Oscillations. This ‘inverse distance ladder’ technique provides an alternative to… read more here.

DOI: 10.1093/mnras/staf308

Abstract: The Hubble constant (H0) is a key parameter in cosmology, yet its precise value remains contentious due to discrepancies between early- and late-universe measurement methods, a problem known as the “Hubble tension.” In this study,… read more here.

DOI: 10.1103/physrevd.110.123518

Abstract: We present an up-to-date compilation of published Hubble constant ($H_0$) measurements that are independent of the CMB sound horizon scale. This compilation is split in two distinct groups: A. Distance Ladder Measurements sample comprising of… read more here.
