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.…
Integrated perturbation theory for cosmological tensor fields. IV. Full-sky formulation
Takahiko Matsubara
In Papers I-III [arXiv:2210.10435, arXiv:2210.11085, arXiv:2304.13304], we use the flat-sky and distant-observer approximations to develop a formalism with which the correlation st…
Deciphering cosmological information from redshift surveys of high-z objects - the cosmological light-cone effect and redshift-space distortion -
Yasushi Suto, Hiromitsu Magira, Y. P. Jing +2
The three-dimensional distribution of astronomical objects observed in redshift space significantly differs from the true distribution since the distance to each object cannot be d…
Analytic Expression of the Genus in Weakly Non-Gaussian Field Induced by Gravity
T. Matsubara
The gravitational evolution of the genus of the density field in large-scale structure is analytically studied in a weakly nonlinear regime using second-order perturbation theory.…
