The Hubble constant from the improved lens modeling of cluster-lensed supernova Refsdal with new spectroscopic redshifts and the Jackknife method
Yuting Liu, Masamune Oguri
Time-delay cosmology offers an alternative approach to measuring the Hubble constant (), which is distinct from the cosmic distance ladder and cosmic microwave background radi…

Assessing the effect of mass-model assumptions on measuring the Hubble constant from the cluster-lensed supernova Refsdal
Yuting Liu, Masamune Oguri
The Hubble constant, , which is a crucial parameter in astrophysics and cosmology, is under significant tension. We explore an independent technique to measure based on…
