Imprint of anisotropic primordial non-Gaussianity on halo intrinsic alignments in simulations
Kazuyuki Akitsu, Toshiki Kurita, Takahiro Nishimichi +2
Using -body simulations of cosmological large-scale structure formation, for the first time, we show that the anisotropic primordial non-Gaussianity (PNG) causes a scale-depende…
Power spectrum of halo intrinsic alignments in simulations
Toshiki Kurita, Masahiro Takada, Takahiro Nishimichi +3
We use a suite of -body simulations to study intrinsic alignments (IA) of halo shapes with the surrounding large-scale structure in the CDM model. For this purpose, we develo…
The impact of projection effects on cluster observables: stacked lensing and projected clustering
Tomomi Sunayama, Youngsoo Park, Masahiro Takada +6
An optical cluster finder inevitably suffers from projection effects, where it misidentifies a superposition of galaxies in multiple halos along the line-of-sight as a single clust…
