The abundance pattern of O, Mg, Si and Fe in the intracluster medium of the Centaurus cluster observed with XMM-Newton
Kyoko Matsushita, Hans Boehringer, Isao Takahashi +1
The abundances of O, Mg, Si and Fe in the intracluster medium of the Centaurus cluster are derived. The Fe abundance has a negative radial gradient. In solar units, the Si abundanc…
X-ray Spectral Study of the extended emission,'the Cap', located 11.6 kpc above the disk of M82
Takeshi Go Tsuru, Midori Ozawa, Yoshiaki Hyodo +11
The extended X-ray emission from 'the Cap' region located 11' (11.6 kpc) above the disk of the starburst galaxy M82 has been observed with Suzaku and XMM-Newton. Owing to the good…
Suzaku Observations of the Centaurus Cluster: Absence of Bulk Motions in the Intracluster Medium
Naomi Ota, Yasushi Fukazawa, Andrew C. Fabian +13
The Centaurus cluster (z=0.0104) was observed with the X-ray Imaging Spectrometer (XIS) onboard the Suzaku X-ray satellite in three pointings, one centered on the cluster core and…
Suzaku observation of the metallicity distribution in the intracluster medium of the Fornax cluster
Kyoko Matsushita, Yasushi Fukazawa, John P. Hughes +10
The metallicity distribution in the Fornax cluster was studied with the XIS instrument onboard the Suzaku satellite. K-shell lines of O and Mg were resolved clearly, and the abunda…
Search for Oxygen Emission from Warm-Hot Intergalactic Medium around A2218 with Suzaku
Yoh Takei, Takaya Ohashi, J. Patrick Henry +12
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…
DIOS: the Diffuse Intergalactic Oxygen Surveyor
T. Ohashi, M. Ishida, S. Sasaki +14
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor), consisting of a 4-stage X-ray telescope and an array of TES microcalorimeters, coole…
