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…
Nulling baryonic feedback in weak lensing surveys using cross-correlations with fast radio bursts
Calvin Leung, Josh Borrow, Kiyoshi W. Masui +4
Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forw…
Field-level Reconstruction from Foreground-Contaminated 21-cm Maps
Shu-Fan Chen, Kai-Feng Chen, Cora Dvorkin
Current and upcoming 21-cm experiments will soon be able to map 21-cm spatial fluctuations in three dimensions for a wide range of redshifts. However, bright foreground contaminati…
Evolution of Massive Red Galaxies in Clusters from z=1.0 to z=0.3
Yen-Ting Lin, Kai-Feng Chen, Tsung-Chi Chen +2
A critical issue in studying the evolution of galaxy clusters is to find ways that enable meaningful comparisons of clusters observed at different redshifts, as well as in various…
Weak-Lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: II. Cosmological Constraints from the Cluster Abundance
I-Non Chiu, Kai-Feng Chen, Masamune Oguri +9
We present cosmological constraints using the abundance of weak-lensing shear-selected galaxy clusters in the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The clusters are sel…
Weak-Lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: I. Cluster Catalog, Selection Function and Mass--Observable Relation
Kai-Feng Chen, I-Non Chiu, Masamune Oguri +9
We present the first step toward deriving cosmological constraints through the abundances of galaxy clusters selected in a weak-lensing aperture mass map, con…
A Systematic Search of Distant Superclusters with the Subaru Hyper Suprime-Cam Survey
Tsung-Chi Chen, Yen-Ting Lin, Hsi-Yu Schive +13
Superclusters, encompassing environments across a wide range of overdensities, can be regarded as unique laboratories for studying galaxy evolution. Although numerous supercluster…
