Research Abstract

We have made quantitative predictions for near-future observations of galaxy clusters by means of detailed simulations for ALMA and ASTRO-H. We have succeeded in clarifying the spatial distributions of dust in an elliptical galaxy and a galaxy group by Spitzer and AKARI, respectively. We have also found a new source of systematic errors in the temperature data of clusters by Chandra. Furthermore, we have developed new scenarios on the early formation of globular clusters and low-metallicity stars by means of radiation-hydrodynamic simulations.
