Acceleration and transport of relativistic electrons in the jets of the microquasar SS 433 [PDF]
ScienceSS 433 is a microquasar, a stellar binary system that launches collimated relativistic jets. We observed SS 433 in gamma rays using the High Energy Stereoscopic System (H.E.S.S.) and found an energy-dependent shift in the apparent position of the gamma ...

Using evolutionary algorithms to model relativistic jets [PDF]
Astronomy & Astrophysics, 2019 Context. High-resolution very long baseline interferometry (VLBI) observations of NGC 1052 show a two sided jet with several regions of enhanced emission and a clear emission gap between the two jets.

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

Sources of Relativistic Jets in the Galaxy [PDF]
, 1999 Black holes of stellar mass and neutron stars in binary systems are first detected as hard X-ray sources using high-energy space telescopes. Relativistic jets in some of these compact sources are found by means of multiwavelength observations with ground-

A powerful hydrodynamic booster for relativistic jets [PDF]
, 2006 Velocities close to the speed of light are a robust observational property of the jets observed in microquasars and AGNs, and are expected to be behind much of the phenomenology of GRBs. Yet, the mechanism boosting relativistic jets to such large Lorentz

Efficient Nonthermal Particle Acceleration by the Kink Instability in Relativistic Jets. [PDF]
Physical Review Letters, 2018 Relativistic magnetized jets from active galaxies are among the most powerful cosmic accelerators, but their particle acceleration mechanisms remain a mystery.

Total and Linearly Polarized Synchrotron Emission from Overpressured Magnetized Relativistic Jets [PDF]
Astrophysical Journal, 2018 We present relativistic magnetohydrodynamic (RMHD) simulations of stationary overpressured magnetized relativistic jets, which are characterized by their dominant type of energy: internal, kinetic, or magnetic.

The Morphology and Dynamics of Relativistic Jets with Relativistic Equation of State
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.

Galaxies, 2019 The particle-in-cell (PIC) method was developed to investigate microscopic phenomena, and with the advances in computing power, newly developed codes have been used for several fields, such as astrophysical, magnetospheric, and solar plasmas.

Relativistic Jets in Core-collapse Supernovae [PDF]
Astrophysical Journal, 2017 After decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. One common mechanism is a neutrino-driven outflow, but others have been proposed.
