SHAPE: cosmology with cluster halo intrinsic alignments from subhalo distributions

Shogo Ishikawa, Atsushi Taruya, Takahiro Nishimichi +2

Galaxy clusters trace the most massive dark matter haloes, whose shapes and orientations reflect the imprint of the cosmic large-scale tidal field. This paper introduces the Subhal…

Inner structure of cold and warm dark matter halos from particle dynamics

Yohsuke Enomoto, Atsushi Taruya, Satoshi Tanaka +1

Using the number of apocenter passages and the radial action of each particle, we characterize the phase-space structure within the multi-stream regions of cold and warm…

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…
