PEGASUS (Pfs Emission-line GAlaxy SUrvey with Subaru): I. Three-dimensional large-scale structures at probed with emission-line galaxies
Mariko Kubo, Tadayuki Kodama, Rhythm Shimakawa +16
To comprehensively understand the environmental effects on galaxy evolution, it is crucial to precisely map the distribution and thoroughly examine the properties of galaxies, incl…
Weak-lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: III. A precision cosmological sample enabled by optical confirmation
I-Non Chiu, Kai-Feng Chen, Masamune Oguri +9
We develop fCAMIRA (forced-mode CAMIRA), a tool for optical cluster confirmation, and apply it to a sample of 129 weak-lensing (WL) shear-selected galaxy clusters identified in ape…
From Dark Matter to Galaxies: Halo-Free Mock Generation via Conditional Point-Cloud Diffusion
Kana Moriwaki, Ken Osato, Naoki Yoshida
We present a diffusion-based generative model for constructing realistic galaxy catalogues from dark matter density fields. The model takes a three-dimensional dark matter density…
Clustering of emission line galaxies with IllustrisTNG -- II. cosmology challenge with anisotropic correlation functions and ELG-halo connections
Ken Osato, Teppei Okumura
Emission line galaxies (ELGs) are the primary tracers of the large-scale structures of the Universe in ongoing Stage-IV cosmological spectroscopic surveys, which aim to measure the…
Cross-correlating galaxies and cosmic dispersion measures: Constraints on the gas-to-halo mass relation from 2MASS galaxies and 133 localized fast radio bursts
Masato Shirasaki, Ryuichi Takahashi, Ken Osato +1
We conduct a cross-correlation analysis between large-scale structures traced by the Two Micron All Sky Survey (2MASS) galaxy catalog and the cosmic dispersion measures of 133 loca…
Denoising weak lensing mass maps with diffusion model and generative adversarial network
Shohei D. Aoyama, Ken Osato, Masato Shirasaki
The matter distribution of the Universe can be mapped through the weak gravitational lensing (WL) effect: small distortions of the shapes of distant galaxies, which reflects the in…
