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.

Stationary relativistic jets. [PDF]
Comput Astrophys Cosmol, 2015 AbstractIn 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 $v_{z}\approx c$ v z

Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes [PDF]
Nature CommunicationsRelativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe. Similar jets from stellar-mass black holes offer a chance to study the phenomena on accessible observation time scales ...

Particle-in-Cell Simulations of Astrophysical Relativistic Jets
Universe, 2021 Astrophysical relativistic jets in active galactic nuclei, gamma-ray bursts, and pulsars is the main key subject of study in the field of high-energy astrophysics, especially regarding the jet interaction with the interstellar or intergalactic ...

Applying Relativistic Reconnection to Blazar Jets
Galaxies, 2016 Rapid and luminous flares of non-thermal radiation observed in blazars require an efficient mechanism of energy dissipation and particle acceleration in relativistic active galactic nuclei (AGN) jets.

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]
Nature CommunicationsRelativistic jets from accreting black holes radiate non-thermal emission which is highly variable in different time scales. Previous studies on black holes of different mass scales, including supermassive and stellar-mass black holes, only report flux ...

Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields
Galaxies, 2016 In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both electron–proton ( e − – p + ) and electron–positron ( e ± )

GRMHD Simulations and Modeling for Jet Formation and Acceleration Region in AGNs
Universe, 2022 Relativistic jets are collimated plasma outflows with relativistic speeds. Astrophysical objects involving relativistic jets are a system comprising a compact object such as a black hole, surrounded by rotating accretion flows, with the relativistic jets
