The Environmental Dependence of Halo Intrinsic Alignments: Stronger Signals in Underdense Regions
Masaya Ichikawa, Jingjing Shi, Toshiki Kurita +3
The intrinsic alignment (IA) of galaxies and the dark matter haloes that host them is one of the leading astrophysical systematics for weak-lensing cosmology, yet how the IA signal…
Modeling survey-window and integral-constraint effects on PNG in the galaxy power spectrum with light-cone mocks
Shintaro Nakano, Masahiro Takada, Toshiki Kurita +1
We develop an analysis framework based on {\em light-cone} galaxy mock catalogs constructed from linear theory simulations in order to accurately model the impact of primordial non…
Fully non-linear simulations of galaxy intrinsic alignments for weak lensing with the MillenniumTNG lightcone
Fulvio Ferlito, Volker Springel, Christopher T. Davies +4
We present a complete forward model of a realistic weak lensing galaxy catalogue based on the 740 Mpc hydrodynamical MillenniumTNG (MTNG) simulation. Starting with a complete parti…
Late-time suppression of structure growth as a solution for the tension
Ryo Terasawa, Masahiro Takada, Toshiki Kurita +1
The value inferred from the Subaru Hyper Suprime-Cam (HSC) Year 3 cosmic shear data, under the assumption of the flat CDM model, is 2-3 lower than that inferred from ob…
Testing small-scale modifications in the primordial power spectrum with Subaru HSC cosmic shear, primary CMB and CMB lensing
Ryo Terasawa, Masahiro Takada, Sunao Sugiyama +1
Different cosmological probes, such as primary cosmic microwave background (CMB) anisotropies, CMB lensing, and cosmic shear, are sensitive to the primordial power spectrum (PPS) o…
Improving redshift-space power spectra of halo intrinsic alignments from perturbation theory
Atsushi Taruya, Toshiki Kurita, Teppei Okumura
Intrinsic alignments (IAs) of galaxies/halos observed via galaxy imaging survey, combined with redshift information, offer a novel probe of cosmology as a tracer of the tidal force…
