On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity
Ryo Terasawa, Yue Nan, Masahiro Takada
We investigate the angular power spectrum ( and angular correlation function () of galaxy number density field in the presence of the local-type primordial non-Gauss…

Exploring the baryonic effect signature in the Hyper Suprime-Cam Year 3 cosmic shear two-point correlations on small scales: the tension remains present
Ryo Terasawa, Xiangchong Li, Masahiro Takada +10
The baryonic feedback effect is considered as a possible solution to the so-called tension indicated in cosmic shear cosmology. The baryonic effect is more significant on sma…

Flat to nonflat: Calculating nonlinear power spectra of biased tracers for nonflat CDM model
Ryo Terasawa, Ryuichi Takahashi, Takahiro Nishimichi +1
The growth of large-scale structure, together with the geometrical information of cosmic expansion history and cosmological distances, can be used to obtain constraints on the spat…
