Forecasting the constraints on optical selection bias and projection effects of galaxy cluster lensing with multiwavelength data
Conghao Zhou, Hao-Yi Wu, Andrés N. Salcedo +12
Galaxy clusters identified with optical imaging tend to suffer from projection effects, which impact richness (the number of member galaxies in a cluster) and lensing coherently. P…
Over-abundance of orphan galaxies in the UniverseMachine
Amit Kumar, Surhud More, Tomomi Sunayama
Orphan galaxies that have lost a large fraction of the dark matter subhaloes have often been invoked in semi-analytical as well as empirical models of galaxy formation. We run a mo…
Dark Energy Survey Year 1 Clusters are Consistent with Planck
Andrés N. Salcedo, Hao-Yi Wu, Eduardo Rozo +4
The recent Dark Energy Survey Year 1 (DES-Y1) analysis of galaxy cluster abundances and weak lensing produced and constraints in 5.6 tension with Planck. It is…
Optical Cluster Cosmology with SDSS redMaPPer clusters and HSC-Y3 lensing measurements
Tomomi Sunayama, Hironao Miyatake, Sunao Sugiyama +9
We present cosmology results obtained from a blind joint analysis of the abundance, projected clustering, and weak lensing of galaxy clusters measured from the Sloan Digital Sky Su…
Robustness of Baryon Acoustic Oscillations Measurements with Photometric Redshift Uncertainties
Keitaro Ishikawa, Tomomi Sunayama, Atsushi J. Nishizawa +2
We investigate the robustness of baryon acoustic oscillations (BAO) measurements with a photometric galaxy sample using mock galaxy catalogues with various sizes of photometric red…
The Intrinsic Alignment of Galaxy Clusters and Impact of Projection Effects
Jingjing Shi, Tomomi Sunayama, Toshiki Kurita +7
Galaxy clusters, being the most massive objects in the Universe, exhibit the strongest alignment with the large-scale structure. However, mis-identification of members due to proje…
Hyper Suprime-Cam Year 3 Results: Cosmology from Galaxy Clustering and Weak Lensing with HSC and SDSS using the Emulator Based Halo Model
Hironao Miyatake, Sunao Sugiyama, Masahiro Takada +31
We present cosmology results from a blinded joint analysis of cosmic shear, , galaxy-galaxy weak lensing, , and projected galaxy clustering, $w_{\rm p}…
Hyper Suprime-Cam Year 3 Results: Cosmology from Cosmic Shear Power Spectra
Roohi Dalal, Xiangchong Li, Andrina Nicola +35
We measure weak lensing cosmic shear power spectra from the three-year galaxy shear catalog of the Hyper Suprime-Cam (HSC) Subaru Strategic Program imaging survey. The shear catalo…
Hyper Suprime-Cam Year 3 Results: Cosmology from Cosmic Shear Two-point Correlation Functions
Xiangchong Li, Tianqing Zhang, Sunao Sugiyama +32
We perform a blinded cosmology analysis with cosmic shear two-point correlation functions (2PCFs) measured from more than 25 million galaxies in the Hyper Suprime-Cam three-year sh…
