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…
Accurate Galaxy Cluster Shear and Mass Calibration for LSST with AnaCal
Conghao Zhou, Xiangchong Li, Hao-Yi Wu +12
The observed abundance of galaxy clusters as a function of mass and redshift provides a powerful route to precision cosmology; a key challenge for cluster cosmology is to establish…
Weak-lensing mass calibration of \emph{Planck} Sunyaev--Zel'dovich clusters with HSC-SSP Year~3
Andrés Alejandro Plazas Malagón, Hironao Miyatake, Surhud More +3
We present a weak gravitational lensing mass calibration of 19 \textit{Planck} Sunyaev--Zel'dovich (SZ) selected galaxy clusters using shape measurements from the Hyper Suprime-Cam…
Golden and Silver Dark Sirens for precise H0 measurement with HETDEX
Yixuan Dang, Ish Gupta, Robin Ciardullo +12
Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…
Cosmology-Independent Constraints on the Etherington Relation and SNeIa Absolute Magnitude Evolution from DESI-DR2
Sourav Das, Surhud More, Shadab Alam
We carry out a test of the fundamental Etherington relation (cosmic distance duality relation) which relates the luminosity distance and angular diameter distance $D_{\…
Hyper Suprime-Cam Y3 results: photo- bias calibration with lensing shear ratios and cosmological constraints from cosmic shear
Divya Rana, Surhud More, Hironao Miyatake +3
We present an independent calibration of the photometric redshift (photo-) distributions for source galaxies in the HSC-Y3 weak lensing survey using small-scale galaxy-galaxy le…
