The DESI DR1/DR2 evidence for dynamical dark energy is biased by low-redshift supernovae
Lu Huang, Rong-Gen Cai, Shao-Jiang Wang
Recently, a preference for dynamical dark energy has been reported by the Dark Energy Spectroscopic Instrument (DESI) collaboration, which has inspired hot debates on ne…

Narrowing down the Hubble tension to the first two rungs of distance ladders
Lu Huang, Rong-Gen Cai, Shao-Jiang Wang +2
The decade-persistent Hubble tension has become a crisis of modern cosmology between the early-Universe extrapolation from globally fitting the standard CDM to Planck-CMB…

No-go guide for the Hubble tension: late-time or local-scale new physics
Lu Huang, Shao-Jiang Wang, Wang-Wei Yu
The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant () tension, which manifests itself as the sound-horizon ($r_…
