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 ...

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

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.

Some Implications of inverse-Compton Scattering of Hot Cocoon Radiation by relativistic jets in Gamma-Ray Bursts [PDF]
, 2014 Long Gamma-Ray Bursts (GRB) relativistic jets are surrounded by hot cocoons which confine jets during their punch out from the progenitor star. These cocoons are copious sources of X-ray photons that can be and are inverse-Compton (IC) scattered to MeV ...

The baryon loading effect on relativistic astrophysical jet transport in the interstellar medium
New Journal of Physics, 2018 The composition of the astrophysical relativistic jets remains uncertain. By kinetic particle-in-cell simulations, we show that the baryon component in the jet, or the so-called baryon loading effect (BLE), heavily affects relativistic jets transport ...

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

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

Relativistic Jets in Gamma-Ray-Emitting Narrow-Line Seyfert 1 Galaxies [PDF]
Galaxies, 2019 Before the launch of the Fermi Gamma-ray Space Telescope satellite only two classes of active galactic nuclei (AGN) were known to generate relativistic jets and thus to emit up to the γ -ray energy range: blazars and radio galaxies, both hosted

Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions [PDF]
EPJ Web of Conferences, 2013 Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.
