On the Difficulties with Late-Time Solutions for the Hubble Tension
Prakhar Bansal, Dragan Huterer
We explore the notion that cosmological models that modify the late-time expansion history cannot simultaneously fit the SH0ES collaboration's measurements of the Hubble constant,…

Expansion-history preferences of DESI DR2 and external data
Prakhar Bansal, Dragan Huterer
We explore the origin of the preference of DESI DR2 baryon acoustic oscillation (BAO) measurements and external data from cosmic microwave background (CMB) and type Ia supernovae (…
