Collisional behaviors of astrophysical collisionless plasmas
TL;DR: In collisional fluids, a number of key processes rely on the frequency of binary collisions as mentioned in this paper, and collisions seem necessary to generate a shock wave when two fluids collide fast enough, to fulfill the Rankine-Hugoniot relations, to establish an equation of state or a Maxwellian distribution.

TL;DR: In this article, a gamma-ray supernova remnant (G349.2) was detected at the distance of 11.5 kpc and observed across the entire electromagnetic spectrum from radio to high energy (HE; 0.7+0.1 GeV 100 GeV).

Magnetic Field Amplification by Collisionless Shocks in Partially Ionized Plasmas
TL;DR: In this paper, the authors studied the shock structures of collisionless shocks in partially ionized plasmas by means of two-dimensional hybrid simulations, where the shock is a perpendicular shock with shock velocity and the upstream ionization fraction is 0.5.
Journal ArticleDOI
Effects of Leakage Neutral Particles on Shocks
TL;DR: In this paper, the effects of neutral particles on shocks propagating into the partially ionized medium were investigated, and it was shown that about ten percent of upstream neutral particles leak into the upstream region from the downstream region.

Active galactic nuclei jets and multiple oblique shock acceleration: starved spectra
Athina Meli,Peter L. Biermann +1 more
TL;DR: In this article, a model of a single injection of particles consecutively accelerated by several oblique shocks along the axis of an active galactic nuclei (AGN) jet was proposed.
