Magnetic Reconnection in Galaxy Clusters
Takuya Akahori, Kohei Kurahara, Shin-ya Nitta +4
Galaxy clusters contain an intra-cluster medium (ICM) with temperatures of tens of millions of Kelvin. Cosmological structure formation simulations show that this diffuse gas is he…
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…
Galaxy clusters at z~1 imaged by ALMA with the Sunyaev-Zel'dovich effect
T. Kitayama, S. Ueda, N. Okabe +15
We present high angular-resolution measurements of the thermal Sunyaev-Zel'dovich effect (SZE) toward two galaxy clusters, RCS J2319+0038 at z=0.9 and HSC J0947-0119 at z=1.1, by t…
Diffuse radio source candidate in CIZA J1358.9-4750
Kohei Kurahara, Takuya Akahori, Ruta Kale +11
We report on results of our upgraded Giant Metrewave Radio Telescope (uGMRT) observations for an early-stage merging galaxy cluster, CIZA J1358.9-4750 (CIZA1359), in Band-3 (300--5…
Discovery of Radio Jets in Phoenix Galaxy Cluster Center
Takuya Akahori, Tetsu Kitayama, Shutaro Ueda +6
We report the results of the Australia Telescope Compact Array (ATCA) 15 mm observation of the Phoenix galaxy cluster possessing an extreme star-burst brightest cluster galaxy (BCG…
Deeply cooled core of the Phoenix galaxy cluster imaged by ALMA with the Sunyaev-Zel'dovich effect
T. Kitayama, S. Ueda, T. Akahori +7
We present measurements of the thermal Sunyaev-Zel'dovich effect (SZE) toward SPT-CL J2334-4243 (the Phoenix galaxy cluster) at z=0.597 by the Atacama Large Millimeter/submillimete…
