Unravelling Turbulence and Magnetic Fields in Galaxy Clusters with SKA and XRISM
Kohei Kurahara, Takuya Akahori, Amit Seta +5
This chapter proposes a research framework to quantitatively investigate non-thermal components in the Intracluster Medium (ICM) of galaxy clusters, which are critical ingredients…
A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…
Origin and Evolution of the Structure in the Head-Tail Radio Galaxy of Abell 3322
Kohei Kurahara, Takuya Akahori, Takumi Ohmura +8
A head-tail galaxy is thought to be a radio galaxy with bent active galactic nuclei (AGN) jets interacting with the intracluster medium (ICM). Study of head-tail galaxies provides…
CO Observations of the Type Ia Supernova Remnant 3C 397 by the Nobeyama 45-m Radio Telescope: Possible Evidence for the Single-Degenerated Explosion
Daisuke Ito, Hidetoshi Sano, Kazuhiro Nakazawa +4
We present a new CO observation toward the Type Ia supernova remnant (SNR) 3C 397 using the Nobeyama 45-m radio telescope at an unprecedent angular resolution of 18''. We new…
