| Abstract: |
The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measure velocities of the intracluster plasma, and extending at the same time the spectral coverage to energies well beyond 10 keV. We present an overview of the capabilities of ASTRO-H for exploring gas motions in galaxy clusters including their cosmological implications, the physics of AGN feedback, the dynamics of cluster mergers and associated high-energy processes, the chemical enrichment of the intracluster medium, and the nature of missing baryons and unidentified dark matter. |
