The Subaru HSC Galaxy Clustering with Photometric Redshift I: Dark Halo Masses Versus Baryonic Properties of Galaxies at 0.3<z<1.4
Shogo Ishikawa, Nobunari Kashikawa, Masayuki Tanaka +8
We present the clustering properties of low- galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over deg. The wide-field and…
Semi-analytic modelling of AGNs: auto-correlation function and halo occupation
Taira Oogi, Hikari Shirakata, Masahiro Nagashima +5
The spatial clustering of active galactic nuclei (AGNs) is considered to be one of the important diagnostics for the understanding of the underlying processes behind their activiti…
Noise reduction for weak lensing mass mapping: An application of generative adversarial networks to Subaru Hyper Suprime-Cam first-year data
Masato Shirasaki, Kana Moriwaki, Taira Oogi +3
We propose a deep-learning approach based on generative adversarial networks (GANs) to reduce noise in weak lensing mass maps under realistic conditions. We apply image-to-image tr…
Slowing down of cosmic growth of supermassive black holes: Theoretical prediction of the Eddington ratio distribution
Hikari Shirakata, Toshihiro Kawaguchi, Taira Oogi +2
We show the Eddington ratio distributions of supermassive black holes at a wide redshift range (0 < z < 8) obtained with a semi-analytic model of galaxy formation. The distribution…
New constraints on red-spiral galaxies from their kinematics in clusters of galaxies
Akinari Hamabata, Taira Oogi, Masamune Oguri +2
The distributions of the pairwise line-of-sight velocity between galaxies and their host clusters are segregated according to the galaxy's colour and morphology. We investigate the…
