Nonrelativistic parallel shocks in unmagnetized and weakly magnetized plasmas
Jacek Niemiec, Martin Pohl, Antoine Bret +1
We present results of 2D3V particle-in-cell simulations of non-relativistic plasma collisions with absent or parallel large-scale magnetic field for parameters applicable to the co…
Mildly relativistic magnetized shocks in electron-ion plasmas -- II. Particle acceleration and heating
Arianna Ligorini, Jacek Niemiec, Oleh Kobzar +7
Particle acceleration and heating at mildly relativistic magnetized shocks in electron-ion plasma are investigated with unprecedentedly high-resolution two-dimensional particle-in-…
Leptonic non-thermal emission from supernova remnants evolving in the circumstellar magnetic field
Iurii Sushch, Robert Brose, Martin Pohl +2
The very-high-energy (VHE; E > 100 GeV) gamma-ray emission observed from a number of Supernova remnants (SNRs) indicates particle acceleration to high energies at the shock of the…
Modification of the formation of high-Mach number electrostatic shock-like structures by the ion acoustic instability
Mark E Dieckmann, Gianluca Sarri, Domenico Doria +2
The formation of unmagnetized electrostatic shock-like structures with a high Mach number is examined with one- and two-dimensional particle-in-cell (PIC) simulations. The structur…
3D Distribution of Molecular Gas in the Barred Milky Way
Martin Pohl, Peter Englmaier, Nicolai Bissantz
We present a new model of the three-dimensional distribution of molecular gas in the Milky Way Galaxy, based on CO line data. Our analysis is based on a gas-flow simulation of the…
The Milky Way Spiral Arm Pattern
Peter Englmaier, Martin Pohl, Nicolai Bissantz
A complete map of the 3D distribution of molecular (CO) gas was constructed using a realistic dynamical model of the gas flow in the barred potential of the Milky Way. The map show…
