The first demonstration of the concept of "narrow-FOV Si/CdTe semiconductor Compton camera"
Yuto Ichinohe, Yuusuke Uchida, Shin Watanabe +14
The Soft Gamma-ray Detector (SGD), to be deployed onboard the {\it ASTRO-H} satellite, has been developed to provide the highest sensitivity observations of celestial sources in th…
The Si/CdTe semiconductor Compton camera of the ASTRO-H Soft Gamma-ray Detector (SGD)
Shin Watanabe, Hiroyasu Tajima, Yasushi Fukazawa +23
The Soft Gamma-ray Detector (SGD) is one of the instrument payloads onboard ASTRO-H, and will cover a wide energy band (60--600 keV) at a background level 10 times better than inst…
Serendipitous discovery of an extended X-ray jet without a radio counterpart in a high-redshift quasar
A. Simionescu, Ł. Stawarz, Y. Ichinohe +6
A recent Chandra observation of the nearby galaxy cluster Abell 585 has led to the discovery of an extended X-ray jet associated with the high-redshift background quasar B3 0727+40…
Suzaku observations of a shock front tracing the western edge of the giant radio halo in the Coma Cluster
Y. Uchida, A. Simionescu, T. Takahashi +5
We present the results of new Suzaku observations of the Coma Cluster, the X-ray brightest, nearby, merging system hosting a well studied, typical giant radio halo. It has been pre…
Deep Chandra observation and numerical studies of the nearest cluster cold front in the sky
N. Werner, J. A. ZuHone, I. Zhuravleva +9
We present the results of a very deep (500 ks) Chandra observation, along with tailored numerical simulations, of the nearest, best resolved cluster cold front in the sky, which li…
A Uniform Contribution of Core-Collapse and Type Ia Supernovae to the Chemical Enrichment Pattern in the Outskirts of the Virgo Cluster
A. Simionescu, N. Werner, O. Urban +3
We present the first measurements of the abundances of -elements (Mg, Si, and S) extending out to beyond the virial radius of a cluster of galaxies. Our results, based on Suzaku…
Prospect for Future MeV Gamma-ray Active Galactic Nuclei Population Studies
Yoshiyuki Inoue, Yasuyuki T. Tanaka, Hirokazu Odaka +5
While the X-ray, GeV gamma-ray, and TeV gamma-ray skies have been extensively studied, the MeV gamma-ray sky is not well investigated after the Imaging Compton Telescope (COMPTEL)…
