Suzaku diagnostics of the energetics in the lobes of the giant radio galaxy 3C 35
Naoki Isobe, Hiromi Seta, Poshak Gandhi +1
The Suzaku observation of a giant radio galaxy 3C 35 revealed faint extended X-ray emission, associated with its radio lobes and/or host galaxy. After careful subtraction of the X-…
The ASTRO-H Mission
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +174
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
Bright X-ray flares from the BL Lac object Mrk 421, detected with MAXI in 2010 January and February
Naoki Isobe, Kousuke Sugimori, Nobuyuki Kawai +28
Strong X-ray flares from the blazar Mrk 421 were detected in 2010 January and February through the 7 month monitoring with the MAXI GSC. The maximum 2 -- 10 keV flux in the January…
Suzaku Observation of the Brightest Broad-Line Radio Galaxy 4C 50.55 (IGR J 21247+5058)
Fumie Tazaki, Yoshihiro Ueda, Yukiko Ishino +4
We report the results from a deep Suzaku observation of 4C 50.55 (IGR J 21247+5058), the brightest broad-line radio galaxy in the hard X-ray (> 10 keV) sky. The simultaneous broad…
MAXI GSC observations of a spectral state transition in the black hole candidate XTE J1752-223
Satoshi Nakahira, Kazutaka Yamaoka, Mutsumi Sugizaki +29
We present the first results on the black hole candidate XTE J1752-223 from the Gas Slit Camera (GSC) on-board the Monitor of All-sky X-ray Image (MAXI) on the International Space…
Evidence of non-thermal X-ray emission from radio lobes of Cygnus A
Y. Yaji, M. S. Tashiro, N. Isobe +5
Using deep Chandra ACIS observation data for Cygnus A, we report evidence of non-thermal X-ray emission from radio lobes surrounded by a rich intra-cluster medium (ICM). The diffus…
