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.…
