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.

通过对阿尔马和ASTRO-H的详细模拟，我们对星系团的近期观测作了定量预测。我们已经成功地澄清了一个椭圆星系和一个星系群的尘埃的空间分布，分别由斯皮策和AKARI。我们还发现了Chandra星系团温度数据中的一个新的系统误差源。此外，我们已经开发了新的方案，通过辐射流体动力学模拟的早期形成的球状星团和低金属量的恒星。
