X-Ray Study of the Outer Region of Abell 2142 with Suzaku
Hoshino, Akio; Sato, Kosuke; Ohashi, Takaya +4 more
We observed outer regions of a bright cluster of galaxies, A 2142, with Suzaku. Temperature and brightness structures were measured out to the virial radius (
Suzaku Metal Abundance Patterns in the Outflow Region of M 82 and the Importance of Charge Exchange
Gandhi, Poshak; Matsushita, Kyoko; Tamagawa, Toru +2 more
We performed spectral analysis of Suzaku data of the galactic disk and outflow regions of the starburst galaxy M 82. Thermal modeling of the central disk regions requires at least three temperature components. The Ly
Cross Spectral Calibration of Suzaku, XMM-Newton, and Chandra with PKS 2155304 as an Activity of IACHEC
Ishida, Manabu; Tsujimoto, Masahiro; Guainazzi, Matteo +6 more
We report on comparisons of the energy responses of the Suzaku XIS, the Chandra HRC and ACIS with the LETG, and the XMM-Newton MOS and pn using simultaneous data of the BL Lac object PKS 2155
The First MAXI/GSC Catalog in the High Galactic-Latitude Sky
Isobe, Naoki; Yamaoka, Kazutaka; Nakagawa, Yujin E. +31 more
We present the first unbiased source catalog of the Monitor of All-sky X-ray Image (MAXI) mission at high Galactic latitudes (
Suzaku and XMM-Newton Observations of the Fornax Cluster: Temperature and Metallicity Distribution
Sato, Kosuke; Nakazawa, Kazuhiro; Ohashi, Takaya +7 more
Suzaku observed a central region and five offset regions within 0.2
A Large X-Ray Flare from a Single Weak-Lined T Tauri Star TWA-7 Detected with MAXI GSC
Isobe, Naoki; Yamaoka, Kazutaka; Nakagawa, Yujin E. +35 more
We present a large X-ray flare from a nearby weak-lined T Tauri star TWA-7 detected with the Gas Slit Camera (GSC) on the Monitor of All-sky X-ray Image (MAXI). The GSC captured X-ray flaring from TWA-7 with a flux of 3
Nature of the Unidentified TeV Source HESS J1614-518, Revealed by Suzaku and XMM-Newton Observations
Matsumoto, Hironori; Sakai, Michito; Yajima, Yukie
We report on new Suzaku and XMM-Newton results concerning HESS J1614
X-Ray Study of Rekindled Accretion in the Classical Nova V2491 Cygni
Drake, Jeremy J.; Tsujimoto, Masahiro; Ness, Jan-Uwe +5 more
We conducted an X-ray spectroscopic study of the classical nova V2491 Cygni using our target-of-opportunity observation data with the Suzaku and XMM-Newton satellites as well as archived data with the Swift satellite. Medium-resolution (
Observation of the Cygnus OB2 Association with Suzaku and Long-Term Light Curves
Kitamoto, Shunji; Murakami, Hiroshi; Yoshida, Masaki
We obtained a Suzaku 41-ks observation of the four brightest early type stars in the Cygnus OB2 association (Cyg OB2 Nos. 5, 8a, 9, and 12). The spectra of two of the stars, Nos. 9 and 12, could be fitted by a two-temperature thin-thermal collisional-ionization equilibrium model, while those of Nos. 5 and 8a required a three-temperature model. Sta…
X-Ray Observation of Mars at Solar Minimum with Suzaku
Ezoe, Yuichiro; Ishikawa, Kumi; Ohashi, Takaya +2 more
Mars was observed in X-rays during 2008 April 3-5 for 82 ks with the Japanese Suzaku observatory. Mars has been known to emit X-rays via the scattering of solar X-rays and via charge exchange between neutral atoms in the exosphere and solar-wind ions. Past theoretical studies suggest that the exospheric neutral density may vary by a factor of up t…
