Simulating the dynamics and non-thermal emission of relativistic magnetized jets I. Dynamics [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We have performed magnetohydrodynamic (MHD) simulations of relativistic jets from supermassive blackholes over a few tens of kpc for a range of jet parameters.

Shock dynamics in relativistic jets [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We present a formalism of the dynamics of internal shocks in relativistic jets where the source has a time-dependent injection velocity and mass-loss rate. The variation of the injection velocity produces a two-shock wave structure, the working surface, that moves along the jet.

New Astronomy Reviews, 2004 Despite substantial observational and theoretical progress over many years, numerous key questions surrounding the topic of relativistic jets remain to be answered. In particular we still do not know how they are ejected from the supermassive black holes that are implicated in their production and we do not know how the ejection of matter at ...

A Comparison of the Morphology and Stability of Relativistic and Nonrelativistic Jets [PDF]
, 1999 We compare results from a relativistic and a nonrelativistic set of 2D axisymmetric jet simulations. For a set of five relativistic simulations that either increase the Lorentz factor or decrease the adiabatic index we compute nonrelativistic simulations

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.

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-

Relativistic X-Ray Jets from the Black Hole X-Ray Binary MAXI J1820+070 [PDF]
Astrophysical Journal, 2020 The black hole MAXI J1820+070 was discovered during its 2018 outburst and was extensively monitored across the electromagnetic spectrum. Following the detection of relativistic radio jets, we obtained four Chandra X-ray observations taken between 2018 ...

On the Relationship between BL-Lacertae Objects and FRI Radio Galaxies [PDF]
, 1993 The idea that Fanaroff-Riley Class~I Radio Galaxies contain core jets with Lorentz factors of the order of a few and are the parent population for BL~Lac Objects is examined, with particular reference to the data on two FRI Radio Galaxies, NGC~315 and ...

Relativistic Jets in Collapsars [PDF]
The Astrophysical Journal, 2003 We examine the propagation of 2-dimensional relativistic jets through the stellar progenitor in the collapsar model for gamma-ray bursts. In agreement with previous studies, we find that relativistic jets are collimated by their passage through the stellar mantle.
