Measurement of Interstellar Polarization and Estimation of Galactic Extinction for the Direction of X-ray Black Hole Binary V404 Cygni
Ryosuke Itoh, Yasuyuki T. Tanaka, Koji S. Kawabata +12
V404 Cygni is a well-known black hole binary candidate thought to have relativistic jets. It showed extreme outbursts on June 2015, characterized by a large amplitude and short tim…
Hard X-ray Spectral Investigations of Gamma-ray Bursts, 120521C and 130606A, at High-redshift z~6
Tetsuya Yasuda, Yuji Urata, Junich Enomoto +1
This study presents the temporal and spectral analysis of the prompt emission of two high-redshift gamma-ray bursts (GRBs), 120521C at and 130606A at , which we…
Remarks on the Rellich inequality
Shuji Machihara, Tohru Ozawa, Hidemitsu Wadade
We study the Rellich inequalities in the framework of equalities. We present equalities which imply the Rellich inequalities by dropping remainders. This provides a simple and dire…
Stability of trace theorems on the sphere
Neal Bez, Chris Jeavons, Tohru Ozawa +1
We prove stable versions of trace theorems on the sphere in with optimal constants, thus obtaining rather precise information regarding near-extremisers. We also obtain stabi…
Atomic displacements and lattice distortion in the magnetic-field-induced charge ordered state of SmRuP
T. Matsumura, S. Michimura, T. Inami +5
Structural properties of SmRuP in the anomalous magnetic ordered phase between K and K in magnetic fields has been studied by x-ray dif…
Ground State Phase Diagram of S=1 Diamond Chains
Kazuo Hida, Ken'ichi Takano
We investigate the ground-state phase diagram of a spin-1 diamond chain. Owing to a series of conservation laws, any eigenstate of this system can be expressed using the eigenstate…
