Revision of the Selection Function of the Optical Redshift Survey using the Sloan Digital Sky Survey Early Data Release: Toward an Accurate Estimate of Source Number Density of Ultra-High Energy Cosmic Rays
H. Yoshiguchi, S. Nagataki, K. Sato +2
If Ultra-High Energy Cosmic Rays (UHECRs) are originated from nearby galaxies, modeling of the distribution of nearby galaxies is important to an accurate estimate the source numbe…
Three-generation study of neutrino spin-flavor conversion in supernova and implication for neutrino magnetic moment
Shin'ichiro Ando, Katsuhiko Sato
We investigate resonant spin-flavor (RSF) conversions of supernova neutrinos which are induced by the interaction of neutrino magnetic moment and supernova magnetic fields. From th…
Supernova relic neutrinos and observational implications for neutrino oscillation
Shin'ichiro Ando, Katsuhiko Sato
We investigate the flux of supernova relic neutrinos (SRN) for several neutrino oscillation models with parameters inferred from recent experimental results. In the calculation, we…
Upper limit on the mass of RX J1856.5--3754 as a possible quark star
Kazunori Kohri, Kei Iida, Katsuhiko Sato
Recent deep Chandra LETG+HRC-S observations suggest the possibility that RX J1856.5--3754 is a compact star whose radiation radius is 3.8--8.2 km. In this paper, we systematically…
Small Scale Clustering in the Isotropic Arrival Distribution of Ultra-High Energy Cosmic Rays and Implications for Their Source Candidates
H. Yoshiguchi, S. Nagataki, S. Tsubaki +1
We present numerical simulations on the propagation of UHE protons with energies of eV in extragalactic magnetic fields over 1 Gpc. We use the ORS galaxy samp…
Microscopic Study of Slablike and Rodlike Nuclei: Quantum Molecular Dynamics Approach
Gentaro Watanabe, Katsuhiko Sato, Kenji Yasuoka +1
Structure of cold dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. We succeeded in showing that the phases with slab-like and r…
