Outline of Final Research Achievements

We performed a large-scale galaxy redshift survey using the new FMOS instrument of Subaru Telescope, and studied dark energy which is an important problem in cosmology. We successfully completed the two-year observing campaign, and got the large scale structure 3D map beyond redshift one for the first time, by using a few thousand galaxies at z ~ 1.5. We are now performing analysis about redshift space distortion, to test the theory of gravitation. The analysis has mostly been completed, and papers are in press, submitted, or in preparation.
