Asymptotic cone of semisimple orbits for symmetric pairs
Kyo Nishiyama
Let G be a reductive algebraic group over the complex field and O_h be a closed adjoint orbit through a semisimple element h. By a result of Borho and Kraft (1979), it is known tha…
The radiative X-ray and gamma-ray efficiencies of rotation powered pulsars
Jacco Vink, Aya Bamba, Ryo Yamazaki
We present a statistical analysis of the X-ray luminosity of rotation powered pulsars and their surrounding nebulae using the sample of Kargaltsev & Pavlov (2008) and we complement…
Optical Behavior of GRB 061121 around its X-Ray Shallow Decay Phase
T. Uehara, M. Uemura, A. Arai +8
Aims. We report on a detailed study of the optical afterglow of GRB 061121 with our original time-series photometric data. In conjunction with X-ray observations, we discuss the or…
Spectral Cross-calibration of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT Data using Gamma-Ray Bursts
T. Sakamoto, V. Pal'shin, K. Yamaoka +20
We report on the spectral cross-calibration results of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT instruments using simultaneously observed gamma-ray bursts (GRBs). This is…
Three-Dimensional Simulations of MHD Turbulence Behind Relativistic Shock Waves and Their Implications for GRBs
Tsuyoshi Inoue, Katsuaki Asano, Kunihito Ioka
Relativistic astrophysical phenomena such as gamma-ray bursts (GRBs) and active galactic nuclei often require long-lived strong magnetic field. Here, we report on three-dimensional…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…
