Stationary relativistic jets. [PDF]
Comput Astrophys Cosmol, 2015 In this paper we describe a simple numerical approach which allows to study the structure of steady-state axisymmetric relativistic jets using one-dimensional time-dependent simulations. It is based on the fact that for narrow jets with vz≈c$v_{z}\approx

PIC methods in astrophysics: simulations of relativistic jets and kinetic physics in astrophysical systems. [PDF]
Living Rev Comput Astrophys, 2021 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, has been further developed for several fields such as astrophysical ...

The Morphology and Dynamics of Relativistic Jets with Relativistic Equation of State [PDF]
The Astrophysical Journal, 2023 We study the effect of plasma composition on the dynamics and morphology of relativistic astrophysical jets. Our work is based on a relativistic total variation diminishing simulation code.

Probing the Internal Structure of Magnetized, Relativistic Jets with Numerical Simulations [PDF]
Galaxies, 2016 From an observational point of view, unveiling the physical processes behind the nature of the jets emanating from radio-loud AGN demands the resolution of the structure across the jet with the highest angular resolutions.

Numerical simulations of relativistic jets [PDF]
Journal of Plasma Physics, 2023 In this paper, we review recent and ongoing work by our group on numerical simulations of relativistic jets. Relativistic outflows in astrophysics are related to dilute, high energy plasmas, with physical conditions out of the reach of current laboratory

Propagation, cocoon formation, and resultant destabilization of relativistic jets [PDF]
Monthly notices of the Royal Astronomical Society, 2019 A cocoon is a by-product of a propagating jet that results from shock heating at the jet head. Herein, considering simultaneous cocoon formation, we study the stability of relativistic jets propagating through the uniform ambient medium. Using a simple

Magnetic Dissipation in Relativistic Jets [PDF]
Galaxies, 2016 The most promising mechanisms for producing and accelerating relativistic jets, and maintaining collimated structure of relativistic jets involve magnetohydrodynamical (MHD) processes.

Magnetized, Relativistic Jets [PDF]
Proceedings of XII Multifrequency Behaviour of High Energy Cosmic Sources Workshop — PoS(MULTIF2017), 2017 Extragalactic relativistic jets are composed by charged particles and magnetic fields, as inferred from the synchrotron emission that we receive from them.
