Constraints on the varying electron mass and early dark energy in light of ACT DR6 and DESI DR2 and the implications for inflation
Yo Toda, Osamu Seto
Primarily motivated by the Hubble tension, we analyze the varying electron mass model and axionlike early dark energy model (EDE) using baryon acoustic oscillation data from DESI D…

Constraints on the simultaneous variation of the fine structure constant and electron mass in light of DESI BAO data
Yo Toda, Osamu Seto
We study the cosmological constraints of the time variation of the electron mass and the fine-structure constant , using data of cosmic microwave background, supernovae li…
