Dark Quest II: A Wide-Coverage Neural Network Emulator of the Nonlinear Matter Power Spectrum Across Extended Cosmologies
Satoshi Tanaka, Takahiro Nishimichi, Yosuke Kobayashi
\textsc{DarkEmulator2} is a neural network emulator of the nonlinear matter power spectrum in a nine-dimensional parameter space, developed as the emulato…
GINKAKU: Scalable Cosmological Structure Formation Simulation Code and Post-processing Pipeline
Takahiro Nishimichi, Satoshi Tanaka, Kohji Yoshikawa
We introduce GINKAKU, a new cosmological -body code developed for the Dark Quest II (DQ2) simulation campaign and designed for controlled ensemble production across the cosmolog…
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…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics
2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23
The last few years have seen the emergence of a wide array of novel techniques for analyzing high-precision data from upcoming galaxy surveys, which aim to extend the statistical a…
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…
