An Effective Theory for Biased Tracers via the Boltzmann-Equation Approach

Tomohiro Fujita, Tomo Takahashi, Sora Yamashita

We develop an effective theory for biased tracers formulated at the level of the Boltzmann equation, providing a unified description of density and velocity bias. We introduce a ge…

Kurtosis consistency relation in large-scale structure as a probe of gravity theories

Sora Yamashita, Takahiko Matsubara, Tomo Takahashi +1

Various gravity theories beyond general relativity have been rigorously investigated in the literature such as Horndeski and degenerate higher-order scalar-tensor (DHOST) theories.…

Big bang nucleosynthesis and early dark energy in light of the EMPRESS $Y_{p}$ results and the $H_{0}$ tension

Tomo Takahashi, Sora Yamashita

Recent measurement of the primordial $^{4}$ He abundance $Y_{p}$ from EMPRESS suggests a cosmological scenario with the effective number of neutrino species deviated from the standard v…
