Disc-Based Estimation of the Local Dark Matter Density and Velocity Distribution in IllustrisTNG50
Hatsume Chujo, Shogo Masaki, Keiko I. Nagao +1
We study the dark matter (DM) density and velocity distribution in the solar neighborhood of Milky Way-like galaxies using the TNG50-1 run of the IllustrisTNG simulation suite. Mil…
Shapes and orientations of massive halos in the statistically anisotropic universe
Shogo Masaki, Yurino Mizuguchi, Shohei Saga +1
We investigate how statistical anisotropy (SA) in matter distributions affects the distributions of shapes and orientations of cluster-sized halos, using cosmological -body simu…
First confirmation of anisotropic halo bias from statistically anisotropic matter distributions
Shogo Masaki, Maresuke Shiraishi, Takahiro Nishimichi +2
We confirm for the first time the existence of distinctive halo bias associated with the quadrupolar type of statistical anisotropy (SA) of the linear matter density field using co…
Galaxy-dark matter connection from weak lensing in imaging surveys: Impact of photometric redshift errors
Navin Chaurasiya, Surhud More, Daichi Kashino +2
The uncertainties in photometric redshifts and stellar masses from imaging surveys affect galaxy sample selection, their abundance measurements, as well as the measured weak lensin…
Galaxy-dark matter connection of photometric galaxies from the HSC-SSP Survey: Galaxy-galaxy lensing and the halo model
Navin Chaurasiya, Surhud More, Shogo Ishikawa +3
We infer the connection between the stellar mass of galaxies from the Subaru Hyper Suprime-Cam (HSC) survey, and their dark matter halo masses and its evolution in two bins of reds…
Subhalo abundance matching using progenitor mass at varying redshift: Two modes of stellar mass growth imprinted into the Subaru HSC galaxy clustering
Shogo Masaki, Daichi Kashino, Shogo Ishikawa +1
We propose a novel subhalo abundance matching (SHAM) model that uses the virial mass of the main progenitor of each (sub)halo as a proxy of the galaxy stellar mass $…
