[HTML][HTML] Combining pre-and post-recombination new physics to address cosmological tensions: case study with varying electron mass and sign-switching …
It has recently been argued that the Hubble tension may call for a combination of both pre-
and post-recombination new physics. Motivated by these considerations, we provide one of …
