LoVoCCS. II. Weak Lensing Mass Distributions, Red-Sequence Galaxy Distributions, and Their Alignment with the Brightest Cluster Galaxy in 58 Nearby X-ray-Luminous Galaxy Clusters
Shenming Fu, Ian Dell'Antonio, Zacharias Escalante +31
The Local Volume Complete Cluster Survey (LoVoCCS) is an on-going program to observe nearly a hundred low-redshift X-ray-luminous galaxy clusters (redshifts and X-ray…
HectoMAP: The Complete Redshift Survey (Data Release 2)
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
HectoMAP is a dense redshift survey of 95,403 galaxies based primarily on MMT spectroscopy with a median redshift . The survey covers 54.64 square degrees in a 1.5$^\cir…
The HectoMAP Cluster Survey: Spectroscopically Identified Clusters and their Brightest Cluster Galaxies (BCGs)
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between BCGs and their host clusters. We base t…
Hundreds of weak lensing shear-selected clusters from the Hyper Suprime-Cam Subaru Strategic Program S19A data
Masamune Oguri, Satoshi Miyazaki, Xiangchong Li +9
We use the Hyper Suprime-Cam Subaru Strategic Program S19A shape catalog to construct weak lensing shear-selected cluster samples. From aperture mass maps covering ~deg$^…
The HectoMAP Redshift Survey: First Data Release
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
HectoMAP is a dense, red-selected redshift survey to a limiting covering 55 square degrees in a contiguous 1.5 strip across the northern sky. This region is also…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
