Flat Λ CDM cosmology is specified by two constant fitting parameters in the late Universe, the Hubble constant H 0 and matter density (today) Ω m . Through fitting ( H 0 , Ω m ) to mock Λ CDM simulations in redshift bins, we confirm that A : = H 20 (1 − Ω m ) and B : = H 20 Ω m distributions spread and contract , respectively, with increasing bin redshift. Noting that A = H 20 − B , the spread in A and contraction in B corresponds to a spread in H 0 , and consequently in Ω m . Restricted to non…

Measurements of the Hubble Constant: Tensions in Perspective

Measurement of the distances to nearby galaxies has improved rapidly in recent decades. The ever-present challenge is to reduce systematic effects, especially as greater distances are probed and the

The Megamaser Cosmology Project. XIII. Combined Hubble Constant Constraints

We present a measurement of the Hubble constant made using geometric distance measurements to megamaser-hosting galaxies. We have applied an improved approach for fitting maser data and obtained
