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…
Gravitational Waves from Q-ball Formation
Takeshi Chiba, Kohei Kamada, Masahide Yamaguchi
We study the detectability of the gravitational waves (GWs) from the Q-ball formation associated with the Affleck-Dine (AD) mechanism, taking into account both of the dilution effe…
What Causes Business Cycles? Analysis of the Japanese Industrial Production Data
Hiroshi Iyetomi, Yasuhiro Nakayama, Hiroshi Yoshikawa +4
We explore what causes business cycles by analyzing the Japanese industrial production data. The methods are spectral analysis and factor analysis. Using the random matrix theory,…
Anomalous He-Gas High-Pressure Studies on Superconducting LaO1-xFxFeAs
W. Bi, H. B. Banks, J. S. Schilling +5
AC susceptibility measurements have been carried out on superconducting LaO1-xFxFeAs for x=0.07 and 0.14 under He-gas pressures to about 0.8 GPa. Not only do the measured values of…
Correlation function for a periodic box-ball system
Jun Mada, Tetsuji Tokihiro
We investigate correlation functions in a periodic box-ball system. For the two point functions of short distance, we give explicit formulae obtained by combinatorial methods. We g…
Observational constraints on the interacting Ricci dark energy model
Masashi Suwa, Takeshi Nihei
We consider an extension of the holographic Ricci dark energy model by introducing an interaction between dark energy and matter. In this model, the dark energy density is given by…
