Synthetic Spectra from Particle-in-cell Simulations of Relativistic Jets containing an initial Toroidal Magnetic Field

Ioana Dutan, Kenichi Nishikawa, Athina Meli +6

The properties of relativistic jets, their interaction with the environment, and their emission of radiation can be self-consistently studied by using collisionless particle-in-cel…

3D PIC Simulations for Relativistic Jets with a Toroidal Magnetic Field

A. Meli, K. Nishikawa, C. Koehn +6

We have investigated how kinetic instabilities such as the Weibel instability (WI), the mushroom instability (MI), and the kinetic Kelvin-Helmholtz instability (kKHI) are excited i…

PIC methods in astrophysics: Simulations of relativistic jets and kinetic physics in astrophysical systems

Kenichi Nishikawa, Ioana Dutan, Christoph Koehn +1

The Particle-In-Cell (PIC) method has been developed by Oscar Buneman, Charles Birdsall, Roger W. Hockney, and John Dawson in the 1950s and, with the advances of computing power, h…

Streamer propagation in the atmosphere of Titan and other N2:CH4 mixtures compared to N2:O2 mixtures

Christoph Köhn, Sasa Dujko, Olivier Chanrion +1

Streamers, thin, ionized plasma channels, form the early stages of lightning discharges. Here we approach the study of extraterrestrial lightning by studying the formation and prop…

The Planck length and the constancy of the speed of light in five dimensional space parametrized with two time coordinates

Christoph Köhn

In relativity and quantum field theory, the vacuum speed of light is assumed to be constant; the range of validity of general relativity is determined by the Planck length. However…
