Simulations of two-temperature jets in galaxy clusters: II. X-ray property of forward shock
Takumi Ohmura, Mami Machida, Hiroki Akamatsu
Forward shocks by radio jets, driven into the intracluster medium, are one of the indicators that can be used to evaluate the power of the jet. Meanwhile high-angular-resolution X-…
A shock near the virial radius of the Perseus Cluster
Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu +6
Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperatu…
X-ray study of the merging galaxy cluster Abell 3411-3412 with XMM-Newton and Suzaku
X. Zhang, A. Simionescu, H. Akamatsu +3
Context: Chandra observations of the Abell 3411-3412 merging system have revealed an outbound bullet-like sub-cluster in the northern part and many surface brightness (SB) edges at…
Unveiling the Galaxy Cluster - Cosmic Web Connection with X-ray observations in the Next Decade
Stephen A. Walker, Daisuke Nagai, A. Simionescu +35
In recent years, the outskirts of galaxy clusters have emerged as one of the new frontiers and unique laboratories for studying the growth of large scale structure in the universe.…
Properties of the cosmological filament between two clusters: A possible detection of a large-scale accretion shock by
H. Akamatsu, Y. Fujita, T. Akahori +7
We report on the results of a observation of the plasma in the filament located between the two massive clusters of galaxies Abell 399 and Abell 401. Abell 399 (=0.0724…
ASTRO-H White Paper - Clusters of Galaxies and Related Science
T. Kitayama, M. Bautz, M. Markevitch +22
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 measu…
Properties of the intracluster medium of Abell 3667 observed with Suzaku XIS
H. Akamatsu, J. de Plaa, J. Kaastra +4
We observed the northwest region of the cluster of galaxies A3667 with the Suzaku XIS instrument. The temperature and surface brightness of the intracluster medium were measured up…
X-ray Temperature and Mass Measurements to the Virial Radius of Abell 1413 with Suzaku
A. Hoshino, J. P. Henry, K. Sato +14
We present X-ray observations of the northern outskirts of the relaxed galaxy cluster A1413 with Suzaku, whose XIS instrument has the low intrinsic background needed to make measur…
