| Outline of Final Research Achievements |
New physical models were implemented in the cosmological hydrodynamic code GADGET3-Osaka, which is being developed by our group, to run large-scale structure formation simulations. In particular, we implemented new models for star formation, supernova feedback, and dust formation/destruction. Cosmological light cone data were generated and analyzed for Lyman-alpha absorption by neutral hydrogen, galaxy-HI correlations, power spectra, and biases. We found that the degree of Lyman-alpha absorption around galaxies is stronger in massive galaxies than in less massive galaxies, and quantitatively evaluated the effect of supernova feedback to be about 30%. We also developed a model to efficiently distribute HI in the N-body simulations.
