Gas bulk motion in the Perseus cluster measured with SUZAKU
Takayuki Tamura, N. Yamasaki, R. Iizuka +8
We present the results from Suzaku observations of the Perseus galaxy cluster, which is relatively close, the brightest in the X-ray sky and a relaxed object with a cool core. A nu…
Discovery of an Outstanding Disk in the cD Galaxy of the Hydra A Cluster
Yutaka Fujita, Nobuhiro Okabe, Kosuke Sato +7
The central cD galaxy of the Hydra A cluster has one of the most powerful active galactic nuclei (AGNs) in the nearby Universe (z <0.2). We report on the discovery of a dust lane i…
Multi-Wavelength Studies of Spectacular Ram Pressure Stripping of a Galaxy. II. Star Formation in the Tail
Masafumi Yagi, Liyi Gu, Yutaka Fujita +5
With multiband photometric data in public archives, we detected four intracluster star-forming regions in the Virgo cluster. Two of them were at a projected distance of 35 kpc away…
Suzaku Studies of Luminosity-Dependent Changes in the Low-Mass X-ray Binary Aquila X-1
Soki Sakurai, Shunsuke Torii, Hirofumi Noda +7
The neutron-star Low-Mass X-ray Binary Aquila X-1 was observed by Suzaku for seven times, from 2007 September 28 to October 30. The observations successfully traced an outburst dec…
Multi-Wavelength Studies of Spectacular Ram Pressure Stripping of a Galaxy: Discovery of an X-ray Absorption Feature
Liyi Gu, Masafumi Yagi, Kazuhiro Nakazawa +5
We report the detection of an X-ray absorption feature near the galaxy M86 in the Virgo cluster. The absorber has a column density of 2-3 E20 /cm^2, and its position coincides with…
Probing of the Interactions Between the Hot Plasmas and Galaxies in Clusters from z=0.1 to 0.9
Liyi Gu, Poshak Gandhi, Naohisa Inada +7
Based on optical and X-ray data for a sample of 34 relaxed rich clusters of galaxies with redshifts of 0.1-0.9, we studied relative spatial distributions of the two major baryon co…
