| Outline of Final Research Achievements |
We utilized data from Subaru FMOS and HSC surveys to study the structure formation in the Universe, and the nature of dark matter. In the beginning, we explored novel methods to probe the particle nature of dark matter and to detect distant galaxies. We then performed a number of cosmological simulations to generate mock galaxy catalogues. Toward the end of this research project, we analysed data from Subaru, combined with data from Fermi gamma-ray observatory and ALMA radio telescope, to place constraints on the annihilation cross-section of dark matter, to place constraints on the growth rate of large-scale structure, and to detect the most distant oxygen line emitter.
