Mildly relativistic magnetized shocks in electron-ion plasmas I. Electromagnetic shock structure
Arianna Ligorini, Jacek Niemiec, Oleh Kobzar +8
Mildly relativistic shocks in magnetized electron-ion plasmas are investigated with 2D kinetic particle-in-cell simulations of unprecedentedly high resolution and large scale for c…
A Proper Discretization of Hydrodynamic Equations in the Cylindrical Coordinates for Astrophysical Simulations
Tomoyuki Hanawa, Yosuke Matsumoto
Cylindrical coordinates are often used in computational fluid dynamics, in particular, when one considers gas flow accreting onto a central object. Although the cylindrical coordin…
Radiation Magnetohydrodynamic Simulations of Sub-Eddington accretion Flows in AGN: Origin of Soft X-ray Excess and Rapid Time Variabilities
Taichi Igarashi, Yoshiaki Kato, Hiroyuki R. Takahashi +3
We investigate the origin of the soft X-ray excess component in Seyfert galaxies observed when their luminosity exceeds 0.1% of the Eddington luminosity (). The e…
Kinetic simulation of nonrelativistic perpendicular shocks of young supernova remnants. IV. Electron heating
Artem Bohdan, Martin Pohl, Jacek Niemiec +4
High Mach number collisionless shocks are found in planetary systems and supernova remnants (SNRs). Electrons are heated at these shocks to the temperature well above the Rankine-H…
Kinetic simulations of nonrelativistic perpendicular shocks of young supernova remnants. III. Magnetic reconnection
Artem Bohdan, Martin Pohl, Jacek Niemiec +4
Fully kinetic two-dimensional particle-in-cell simulations are used to study electron acceleration at high-Mach-number nonrelativistic perpendicular shocks. SNR shocks are mediated…
Quantum Paraelectricity in the Kitaev Quantum-Spin-Liquid Candidates HLiIrO and DLiIrO
K. Geirhos, P. Lunkenheimer, M. Blankenhorn +7
H3LiIr2O6 is the first honeycomb-lattice system without any signs of long-range magnetic order down to the lowest temperatures, raising the hope for the realization of an ideal Kit…
