One of the advantages of the X-ray Imaging Spectrometer (XIS) system on board Suzaku is its low and stable non-X-ray background (NXB). In order to make the best use of this advantage, modeling the...

High Metallicity of the X-Ray Gas up to the Virial Radius of a Binary Cluster of Galaxies: Evidence of Galactic Superwinds at High-Redshift (2007)

Fujita, Yutaka, Tawa, Noriaki, Hayashida, Kiyoshi, Takizawa, Motokazu, Matsumoto, Hironori, Okabe, Nobuhiro, ...

We present an analysis of a Suzaku observation of the link region between the galaxy clusters A399 and A401. We obtained the metallicity of the intracluster medium (ICM) up to the cluster virial...

Search for Oxygen Emission from Warm-Hot Intergalactic Medium around A2218 with Suzaku (2006)

Takei, Yoh, Ohashi, Takaya, Henry, J. Patrick, Mitsuda, Kazuhisa, Fujimoto, Ryuichi, Tamura, Takayuki, ...

We searched for redshifted O emission lines from the possible warm-hot intergalactic medium (WHIM) surrounding the cluster of galaxies A2218 at z=0.1756 using the XIS instrument on Suzaku. This...
