Active Galactic Nuclei: Jets as the Source of Hadrons and Neutrinos
Acta Polytechnica CTU Proceedings, 2014 Active galactic nuclei are extragalactic sources, and their relativistic hot-plasma jets are believed to be the main candidates of the cosmic-ray origin, above the so-called knee region of the cosmic-ray spectrum.

Effects of Ambient Medium Profiles on the Evolution of Relativistic Magnetized Jets
The Astrophysical JournalRelativistic radio-galaxy jets are conventionally divided into two morphological classes: FR I and FR II. Among them, FR I jets have relatively low radio luminosities and edge-darkened morphologies, indicating they undergo substantial deceleration and ...

The Astrophysical JournalSpinning supermassive black holes (BHs) in active galactic nuclei magnetically launch relativistic collimated outflows, or jets. Without angular momentum supply, such jets are thought to perish within 3 orders of magnitude in distance from the BH, well ...

Ausbreitung von Jets und Entstehung von Machkegeln in (3+1) dimensionaler idealer Hydrodynamik [PDF]
, 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.

The Astrophysical JournalThe 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

A Simulation Study of Low-power Relativistic Jets: Flow Dynamics and Radio Morphology of FR-I Jets
The Astrophysical JournalRadio galaxies are classified into two primary categories based on their morphology: center-brightened FR-I and edge-brightened FR-II. It is believed that the jet power and interactions with the ambient medium govern the deceleration and decollimation of

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 ...
