Hard X-ray Properties of the Merging Cluster Abell 3667 as Observed with Suzaku
Kazuhiro Nakazawa, Craig L. Sarazin, Madoka Kawaharada +10
Wide-band Suzaku data on the merging cluster Abell 3667 were examined for hard X-ray emission in excess to the known thermal component. Suzaku detected X-ray signals in the wide en…
Suzaku Results on the Obscured Low-Luminosity Active Galactic Nucleus in NGC 4258
Shin'ya Yamada, Takeshi Itoh, Kazuo Makishima +1
In 2006 June, the obscured low luminosity active galactic nucleus in the nearby Seyfert 1.9 galaxy NGC 4258 was observed with Suzaku for ~ 100 ks. Utilizing the XIS and the HXD, th…
High energy resolution hard X-ray and gamma-ray imagers using CdTe diode devices
Shin Watanabe, Shin-nosuke Ishikawa, Hiroyuki Aono +8
We developed CdTe double-sided strip detectors (DSDs or cross strip detectors) and evaluated their spectral and imaging performance for hard X-rays and gamma-rays. Though the doubl…
Suzaku Observations of SGR 1900+14 and SGR 1806-20
Yujin E. Nakagawa, Tatehiro Mihara, Atsumasa Yoshida +8
Spectral and timing studies of Suzaku ToO observations of two SGRs, 1900+14 and 1806-20, are presented. The X-ray quiescent emission spectra were well fitted by a two blackbody fun…
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…
Study of Nonthermal Emission from SNR RX J1713.7-3946 with Suzaku
Takaaki Tanaka, Yasunobu Uchiyama, Felix A. Aharonian +11
We present results obtained from a series of observations of the supernova remnant RX J1713.7-3946 by the Suzaku satellite. The observations cover about two-thirds of the remnant s…
