Outline of Final Research Achievements

To clarify the links among the properties of ionized gas, dark matter, stars and AGNs in galaxy clusters, we have utilized multi-wavelength astrophysical data and state-of-the-art cosmological numerical simulations. Our main achievements are that we have successfully measured the Sunyaev-Zel'dovich effect from three galaxy clusters at 5 arcsec resolution, verified the presence of a galaxy cluster that hosts a radiative cooling flow, and shown that dipolar perturbations of gas density and temperature are present ubiquitously even in apparently relaxed galaxy clusters.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、従来困難視されていたスニヤエフ‐ゼルドビッチ効果の高解像度測定が、多数の天体に対して一般的に実現可能であり、特に遠方宇宙における階層構造の進化を解明するための強力な手段となることが立証されたと言える。
