A Large Sky Survey Project and the Related Big Data Analysis
We explore the frontier of statistical computaional cosmology using the large imaging data delivered by Subaru Hyper-Suprime-Cam (HSC) Survey. The large sky usrvey is led by an international group and will utilizes the 8.3-meter telescope Subaru for 300 nights during the period of 2014 to 2019. Deep images of a large fraction of sky over one thousand square degrees will be collected. Our objectives here are of two folds: we analyse the images of about a half billion galaxies to reconstruct the distribution of cosmic dark matter, and we detect a few hundred supernovae that can be used as distance indicators. Combined together, these two data will enable us to derive fundamental parameters, the so-called cosmological paramaters, and to predict the evolution of the universe to the future.
