Overdensity of X-ray Sources in the Field of Nearby Clusters of Galaxies
Murat Hudaverdi, Hideyo Kunieda, Takeshi Tanaka +4
Two nearby clusters of galaxies: A194 (z=0.018) and A1060 (z=0.0114) have been analyzed for their X-ray point source properties with XMM-Newton EPIC-PN data. A multi-band source de…
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…
ASCA and XMM-Newton Observations of A2029
S. Miyoshi, N. Tanaka, M. Yoshimura +4
The X-ray data of A2029 obtained with XMM-Newton show no evidence of an embedded AGN in the central region of this cluster, which was suggested from the analysis of restored ASCA i…
Future Japanese missions for the study of warm-hot intergalactic medium
T. Ohashi, M. Ishida, S. Sasaki +10
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor) to perform survey observations of warm-hot intergalactic medium using OVII and OVIII…
Searching for cosmic missing baryons with DIOS -- Diffuse Intergalactic Oxygen Surveyor --
Yasushi Suto, Kohji Yoshikawa, Noriko Y. Yamasaki +9
Approximately 30 to 50 percent of the total baryons in the present universe is supposed to take a form of warm/hot intergalactic medium (WHIM) whose X-ray continuum emission is ver…
Spatial Distributions of A3558 in the Core Region of the Shapley Supercluster
F. Akimoto, K. Kondou, A. Furuzawa +2
The core region is dominated by three rich Abell clusters and two poor clusters. Their spatial distributions of gas temperature and metal abundance provide us with information on t…
