The Nature of Unresolved Soft X-ray Emission from the Galactic Disk
K. Masui, K. Mitsuda, N. Y. Yamasaki +4
Although about 40% of the soft X-ray background emission in 0.4 to 1 keV range has extragalactic origins and thus is totally blocked by the Galactic absorption in midplane directio…
Iron Emission Lines on the Galactic Ridge Observed with Suzaku
Shigeo Yamauchi, Ken Ebisawa, Yasuo Tanaka +5
In order to elucidate origin of the Galactic Ridge X-ray Emission, we analyzed Suzaku data taken at various regions along the Galactic plane and studied their Fe-K emission line fe…
The NeXT Mission
T. Takahashi, R. Kelley, K. Mitsuda +28
The NeXT (New exploration X-ray Telescope), the new Japanese X-ray Astronomy Satellite following Suzaku, is an international X-ray mission which is currently planed for launch in 2…
On the lack of strong O-line excess in the Coma cluster outskirts from Suzaku
Yoh Takei, Eric D. Miller, Joel N. Bregman +6
About half of the baryons in the local Universe are thought to reside in the so-called warm-hot intergalactic medium (WHIM) at temperatures of 0.1-10 million K. Thermal soft excess…
Type Ia and II supernovae contributions to the metal enrichment in intra-cluster medium observed with Suzaku
Kosuke Sato, Kazuyo Tokoi, Kyoko Matsushita +4
We studied the properties of the intra-cluster medium (ICM) in two clusters of galaxies (AWM 7 and Abell 1060) and two groups (HCG 62 and NGC 507) with the X-ray Observatory Suzaku…
Evidence for Solar-Wind Charge-Exchange X-Ray Emission from the Earth's Magnetosheath
Ryuichi Fujimoto, Kazuhisa Mitsuda, Dan McCammon +7
We report an apparent detection of the C VI 4p to 1s transition line at 459 eV, during a long-term enhancement (LTE) in the Suzaku north ecliptic pole (NEP) observation of 2005 Sep…
