Suzaku X-Ray Imaging and Spectroscopy of Cassiopeia A
Y. Maeda, Y. Uchiyama, A. Bamba +26
Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, includi…
Observation of TeV Gamma Rays from the Fermi Bright Galactic Sources with the Tibet Air Shower Array
M. Amenomori, X. J. Bi, D. Chen +81
Using the Tibet-III air shower array, we search for TeV gamma-rays from 27 potential Galactic sources in the early list of bright sources obtained by the Fermi Large Area Telescope…
Space efficient opposed-anvil high-pressure cell and its application to optical and NMR measurements up to 9 GPa
Kentaro Kitagawa, Hirotada Gotou, Takehiko Yagi +4
We have developed a new type of opposed-anvil high pressure cell with substantially improved space efficiency. The clamp cell and the gasket are made of non-magnetic Ni-Cr-Al alloy…
GRB 070518: A Gamma-ray Burst with Optically Dim Luminosity
L. P. Xin, W. K. Zheng, J. Wang +6
We present our optical observations of {\em Swift} GRB 070518 afterglow obtained at the 0.8-m Tsinghua University-National Astronomical Observatory of China telescope (TNT) at Xing…
Quantum Phase Transitions in Alternating-Bond Mixed Diamond Chains with Spins 1 and 1/2
Kazuo Hida, Ken'ichi Takano, Hidenori Suzuki
We investigate the mixed diamond chain composed of spins 1 and 1/2 when the exchange interaction is alternatingly distorted. Depending on the strengths of frustration and distortio…
Swifts GRB GRB071010B : outlier of the and correlations
Yuji Urata, Kuiyun Huang, Myungshin Im +12
We present multi-band results for GRB071010B based on \Swift, \Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the ${\rm…
