Cosmic Shear constraints from HSC Year 3 with clustering calibration of the tomographic redshift distributions from DESI
J. Choppin de Janvry, B. Dai, S. Gontcho A Gontcho +2
We reanalyze cosmological constraints from Hyper Suprime-Cam (HSC) Y3 shear-shear correlation function using new calibration of the tomographic redshift distribution via the cluste…

Full calibration of the tomographic redshift distribution from the HSC PDR3 Shape Catalog with DESI
J. Choppin de Janvry, S. Gontcho A Gontcho, U. Seljak +53
The calibration of tomographic redshift distributions is essential for cosmological analysis of weak lensing data. In this work, we calibrate all four tomographic bins of the Hyper…
