Constraints on sterile neutrinos and the cosmological tensions
Supriya Pan, Osamu Seto, Tomo Takahashi +1
We investigate cosmological bounds on sterile neutrino masses in the light of the Hubble and tensions. We argue that non-zero masses for sterile neutrinos are inferred at 2$σ…

Impact of big bang nucleosynthesis on the H0 tension
Tomo Takahashi, Yo Toda
We investigate the impact of big bang nucleosynthesis (BBN) on the Hubble tension, focusing on how the treatment of the reaction rate and observational data affect the evaluation o…

Variation of the fine structure constant in the light of recent helium abundance measurement
Osamu Seto, Tomo Takahashi, Yo Toda
We point out that the recent result of primordial helium-4 (He) abundance measurement by EMPRESS, which has reported a smaller He abundance than other measurements, can be…
