TL;DR: This review adresses the physics of shock formation, shock dynamics and particle acceleration based on a close examination of available multi-wavelength or in situ observations, analytical and numerical developments and focuses on the different instabilities triggered during the shock formation and in association with particle acceleration processes.

TL;DR: In this article, a review of recent advances in relativistic beam-plasma instabilities is presented from both theoretical and numerical points of view, focusing on the potentially dominant waves propagating obliquely to the beam direction.

TL;DR: In this paper, a review of the physics of collisionless shock microphysics is presented, focusing on the different instabilities triggered during the shock formation and in association with particle acceleration processes with regards to the properties of the background upstream medium.

TL;DR: This work identifies the most unstable mode on the two-stream or filamentation branch as the main trigger for filamentation and sets both the characteristic transverse and longitudinal filamentation scales in the nonresistive initial stage.

TL;DR: This study investigates the linear stability of the system formed by an electron beam and its return plasma current within a general framework, namely, for any orientation of the wave vector k with respect to the beam and without any a priori assumption on the orientation ofThe electric field withrespect to k .
