Addressing $H_0$ tension with emergent dark radiation in unitary gravity

13 Jul 2020 Barker W. E. V. Lasenby A. N. Hobson M. P. Handley W. J.

We propose a one-parameter extension to $\Lambda$CDM, expected to strongly affect cosmological tensions. An effective dark radiation component in the early universe redshifts away as hot dark matter, then quintessence, tracking the dominant equation-of-state parameter and leaving a falsifiable torsion field in the current epoch...
