In Inoue Laboratory, we study various phenomena on cosmological scales using theoretical and observational methods, in order to elucidate unknown physical laws and mechanisms in the Universe. In particular, we focus on the bending of light paths due to general relativistic effects (gravitational lensing) and changes in light energy (gravitational redshift), and verify the consistency of cosmological models through synergy between theory and observations. In recent years, we have been focusing on observational studies with the ALMA and Subaru telescopes, including verification of dark matter models, galaxy evolution in extremely large-scale low-density regions, deep learning for detecting astronomical objects, and the effect of active galactic nuclei (AGN) on galaxy formation.
