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.

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

Probing the Internal Structure of Magnetized, Relativistic Jets with Numerical Simulations
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.

Relativistic stellar jets: dynamics and non-thermal radiation
EPJ Web of Conferences, 2013 Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.
