Wigner function shapelets: Symplectic representation of astronomical images
Shun Arai
We extend shapelets for the analysis of astronomical images to be available in a phase space, introducing \textit{Wigner function shapelets}(WFSs). Whereas conventional shapelets e…
Catalogs of optically-selected clusters and photometric luminous red galaxies from the Hyper Suprime-Cam Subaru Strategic Program final year dataset
Masamune Oguri, Yen-Ting Lin, Nobuhiro Okabe +9
We construct samples of optically-selected clusters and photometric luminous red galaxies (LRGs) from the Hyper Suprime-Cam Subaru Strategic Program final year dataset covering $\s…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray stacking analysis of Subaru's optically selected clusters spanning low richness regime
N. T. Nguyen-Dang, N. Ota, N. Okabe +17
This is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the SRG/eROS…
Luminosity-Dependent Assembly Bias of Central Galaxies from Weak Lensing and Clustering
Zhenjie Liu, Hironao Miyatake, Joop Schaye +3
Assembly bias, which is the variation in halo clustering at fixed mass driven by formation history, has long been predicted by numerical simulations but remains difficult to confir…
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…
Euclid: Early Release Observations. Weak gravitational lensing analysis of Abell 2390
T. Schrabback, G. Congedo, R. Gavazzi +196
The Euclid space telescope of the European Space Agency (ESA) is designed to provide sensitive and accurate measurements of weak gravitational lensing distortions over wide areas o…
