| Research Abstract |
To reveal the dynamical evolution of the largest objects in the Universe called "clusters of galaxies", an X-ray spectroscopy with the Suzaku satellite has been performed. Since the clusters of galaxies contain a large amount of hot gas, it is possible to measure the motion and temperature of the gas in detail. In particular, we have confirmed, for the first time, the presence of the hottest gas (with temperature of 0.3 billion degree) in the Universe inside the RXJ1347 cluster with the X-ray observations.
