The stellar mass in and around isolated central galaxies: connections to the total mass distribution through galaxy-galaxy lensing in the Hyper Suprime-Cam survey
Wenting Wang, Xiangchong Li, Jingjing Shi +7
Using photometric galaxies from the HSC survey, we measure the stellar mass density profiles for satellite galaxies as a function of the projected distance, , to isolated cent…
Hundreds of weak lensing shear-selected clusters from the Hyper Suprime-Cam Subaru Strategic Program S19A data
Masamune Oguri, Satoshi Miyazaki, Xiangchong Li +9
We use the Hyper Suprime-Cam Subaru Strategic Program S19A shape catalog to construct weak lensing shear-selected cluster samples. From aperture mass maps covering ~deg$^…
A comparative study of satellite galaxies in Milky Way-like galaxies from HSC, DECaLS and SDSS
Wenting Wang, Masahiro Takada, Xiangchong Li +10
We conduct a comprehensive and statistical study of the luminosity functions (LFs) for satellite galaxies, by counting photometric galaxies from HSC, DECaLS and SDSS around isolate…
FPFS Shear Estimator: Systematic Tests on the Hyper Suprime-Cam Survey First Year Data
Xiangchong Li, Masamune Oguri, Nobuhiko Katayama +6
We apply the Fourier Power Function Shapelets (FPFS) shear estimator to the first year data of the Hyper Suprime-Cam survey to construct a shape catalog. The FPFS shear estimator h…
Second Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +62
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru Telescope. The release in…
The stellar halo of isolated central galaxies in the Hyper Suprime-Cam imaging survey
Wenting Wang, Jiaxin Han, Alessandro Sonnenfeld +14
We study the faint stellar halo of isolated central galaxies, by stacking galaxy images in the HSC survey and accounting for the residual sky background sampled with random points.…
