Limited Impact of CMB B-mode Polarization on Constraints on Cosmic Topology
Ryota Himeno, Atsushi J. Nishizawa, Kiyotomo Ichiki
The global spatial structure of the universe is a fundamental question in cosmology. Although the standard model usually assumes a trivial topology, a multiply connected universe c…
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…
Standard Reconstruction Shifts the Optimal Input Scale for CNN-Based Density-Field Reconstruction
Koichiro Nakashima, Kiyotomo Ichiki, Atsushi J. Nishizawa
We investigate convolutional neural network (CNN) methods for reconstructing the high-redshift density field from late-time large-scale structure, focusing on how the physical scal…
