Outline of Final Research Achievements

We constrained general relativity at cosmological scales by making use of the redshift-space distortion over a wide range of scales in the three-dimensional clustering of galaxies observed in Baryon Oscillation Spectroscopic Survey (BOSS) in Sloan Digital Sky Survey III (SDSS-III, 2009-2014). We find no evidence of violation in general relativity and also derive a stringent constraint on neutrino masses. Through the research, we develop a way to predict the distribution of dark matter halos, and also develop a novel way to connect simulated dark matter halos with the observed BOSS galaxies.
