Spectroscopy along Multiple, Lensed Sightlines through Outflowing Winds in the Quasar SDSS J1029+2623
Toru Misawa, Naohisa Inada, Ken Ohsuga +3
We study the origin of absorption features on the blue side of the C IV broad emission line of the large-separation lensed quasar SDSS J1029+2623 at z_em ~ 2.197. The quasar images…
Non-Abelian dual superconductivity in SU(3) Yang-Mills theory: dual Meissner effect and type of the vacuum
Akihiro Shibata, Kei-Ichi Kondo, Seikou Kato +1
We have proposed the non-Abelian dual superconductivity picture for quark confinement in the SU(3) Yang-Mills (YM) theory, and have given numerical evidences for the restricted-fie…
Explicit-Implicit Scheme for Relativistic Radiation Hydrodynamics
Hiroyuki R. Takahashi, Ken Ohsuga, Yuichiro Sekiguchi +2
We propose an explicit-implicit scheme for numerically solving Special Relativistic Radiation Hydrodynamic (RRHD) equations, which ensures a conservation of total energy and moment…
Finite-size scaling in nucleon axial charge from 2+1-flavor DWF lattice QCD
Meifeng Lin, Shigemi Ohta
We report the current status of the on-going lattice-QCD calculations of nucleon isovector axial charge, g_A, using the RBC/UKQCD 2+1-flavor dynamical domain-wall fermion ensembles…
Modeling line-driven disk wind for broad absorption lines of quasars
Mariko Nomura, Ken Ohsuga, Keiichi Wada +2
The disk wind, which is powered by the radiation force due to spectral lines (line force), is studied for broad absorption line (BAL) quasars. We investigate the structure of the d…
Spiral Arms in the Asymmetrically Illuminated Disk of MWC 758 and Constraints on Giant Planets
C. A. Grady, T. Muto, J. Hashimoto +71
We present the first near-IR scattered light detection of the transitional disk associated with the Herbig Ae star MWC 758 using data obtained as part of the Strategic Exploration…
