First Cosmology Results from HSC

The first Cosmic shear measurements from the Hyper Supreme Cam Survey (HSC) on Subaru are now on the arXive (Hikage et al. 2018) !! This paper is the culmination of a tremendous effort of many scientists across the globe and a testimony to the beautiful data quality of the HSC camera on the Subaru Telescope. The HSC cosmic shear results are in agreement with Planck. However, interestingly, in a similar fashion to several other lensing surveys, the constraints in terms of the Sigma8 and OmegaM parameters are slightly offset. A consistent reanalysis of various lensing data sets, and higher signal-to-noise constraints from the full HSC data set will help to rule out or confirm this much discussed offset. More details can be found in our press release.
