Hydrodynamic interactions of relativistic extragalactic jets with dense clouds

, 2015
We have studied three-dimensional hydrodynamic interactions of relativistic extragalactic jets with two-phase ambient media. These jets propagate through a denser homogeneous gas and then impact clouds with densities 100 to 1000 times higher than the ...

Relativistic jets and gamma-ray bursts from neutron star mergers [PDF]

, 2023
A defining characteristic of gamma-ray bursts (GRBs) is the presence of jetted outflows. These jets are shaped by their launching mechanism and interactions with the environment (both close and further distant) of the GRB, as revealed to us when the jets

Synchrotron-limited Particle Acceleration in Relativistic Shearing Flows

The Astrophysical Journal
Fermi-type shear particle acceleration is a promising mechanism for sustaining ultrarelativistic particles along the kiloparsec scale jets in active galactic nuclei.

Ausbreitung von Jets und Entstehung von Machkegeln in (3+1) dimensionaler idealer Hydrodynamik

, 2009
This thesis investigates the jet-medium interactions in a Quark-Gluon Plasma using a hydrodynamical model. Such a Quark-Gluon Plasma represents a very early stage of our universe and is assumed to be created in heavy-ion collisions.

Propagation of Gamma-Ray Burst Relativistic Jets in Active Galactic Nucleus Disks and Its Implication for Gamma-Ray Burst Detection

The Astrophysical Journal
The accretion disks of supermassive black holes (SMBHs) harboring in active galactic nuclei (AGN) are considered to be an ideal site for producing different types of gamma-ray bursts (GRBs). The detectability of these GRB phenomena hidden in AGN disks is

Morphology and dynamics of relativistic jets

, 1995
We present a comprehensive analysis of the morphology and dynamics of relativistic pressure-matched axisymmetric jets. The numerical simulations have been carried out with a high-resolution shock-capturing hydro-code based on an aprpoximate relativistic ...

Knots in Relativistic Transverse Stratified Jets

Galaxies, 2017
We investigate the plasmoid knot formation in stratified relativistic jet by means of relativistic magneto-hydrodynamics simulations. Indeed, astrophysical jets in active galactic nuclei (AGN) seem to be transversely stratified, with a fast inner jet and

Imaging simulated relativistic radio jets.

, 2002
Flux maps of simulated relativistic jets are presented. Both 2-D axially symmetric (Duncan & Hughes, 1994: ApJ, 436, L119) and 3-D (Hardee, et al., 2001: ApJ, 555, 744 and Hughes, et al., 2002, ApJ, 572, in press) jets are examined.
