Precision cosmology with redshift-space bispectrum: a perturbation theory based model at one-loop order
Ichihiko Hashimoto, Yann Rasera, Atsushi Taruya
The large-scale matter distribution in the late-time Universe exhibits gravity-induced non-Gaussianity, and the bispectrum, three-point cumulant is expected to contain significant…
Constraining equilateral-type primordial non-Gaussianities from imaging surveys
Ichihiko Hashimoto, Shuntaro Mizuno, Shuichiro Yokoyama
We investigate expected constraints on equilateral-type primordial non-Gaussianities from future/ongoing imaging surveys, making use of the fact that they enhance the halo/galaxy b…
Constraining higher-order parameters for primordial non-Gaussianities from power spectra and bispectra of imaging survey
Ichihiko Hashimoto, Atsushi Taruya, Takahiko Matsubara +2
We investigate the statistical power of higher-order statistics and cross-correlation statistics to constrain the primordial non-Gaussianity from the imaging surveys. In particular…
