Non-relativistic Collisionless Shocks in Unmagnetized Electron-Ion Plasmas
Tsunehiko N. Kato, Hideaki Takabe
We show that the Weibel-mediated collisionless shocks are driven at non-relativistic propagation speed (0.1c < V < 0.45c) in unmagnetized electron-ion plasmas by performing two-dim…
Formation of Pillars at the Boundaries between H II Regions and Molecular Clouds
Akira Mizuta, Jave O. Kane, Marc W. Pound +3
We investigate numerically the hydrodynamic instability of an ionization front (IF) accelerating into a molecular cloud, with imposed initial perturbations of different amplitudes.…
Compton Spectrum from Poynting Flux Accelerated e+e- Plasma
Shinya Sugiyama, Edison Liang, Koichi Noguchi +1
We report the Compton scattering emission from the Poynting flux acceleration of electron- positron plasma simulated by the 2-1/2 dimensional particle-in-cell(PIC) code. We show th…
Nonaxisymmetric Magnetorotational Instability in Proto-Neutron Stars
Youhei Masada, Takayoshi Sano, Hideaki Takabe
We investigate the stability of differentially rotating proto-neutron stars (PNSs) with a toroidal magnetic field. Stability criteria for nonaxisymmetric MHD instabilities are deri…
Hydrodynamic instability of ionization fronts in HII regions
Akira Mizuta, Jave O. Kane, Marc W. Pound +3
We investigate hydrodynamic instability of accelerating ionization fronts using two dimensional hydrodynamic simulations that include detailed energy deposition and release due to…
Propagation and Dynamics of Relativistic Jets
Akira Mizuta, Shoichi Yamada, Hideaki Takabe
We investigate the dynamics and morphology of jets propagating into the interstellar medium using 2D relativistic hydrodynamic simulations. The calculations are performed assuming…
