Relativistic Jets in Radio-Weak Quasars and LINER Galaxies

, 1997
: We discuss radio observations of a sample of radio-weak and radio-intermediate quasars which demonstrate that -- just like their radio-loud counterparts -- radioweak quasars too have relativistic jets in their nuclei.

Large-scale, decelerating, relativistic X-ray jets from the microquasar XTE J1550-564

, 2002
We have detected, at x-ray and radio wavelengths, large-scale moving jets from the microquasar XTE J1550-564. Plasma ejected from near the black hole traveled at relativistic velocities for at least 4 years.

Numerical Hydrodynamics of Relativistic Extragalactic Jets

, 2007
This dissertation describes a multidimensional relativistic hydrodynamic code which solves the special relativistic hydrodynamic equations as a hyperbolic system of conservation laws based on the total variation diminishing (TVD) scheme. Several standard

Multiple Emission Regions in Jets of the Low-Luminosity Active Galactic Nucleus in NGC 4278

The Astrophysical Journal
The Large High Altitude Air Shower Observatory (LHAASO) has detected very-high-energy gamma rays from the low-ionization nuclear emission-line region galaxy NGC 4278, which has a low-luminosity active galactic nucleus (LLAGN) and symmetric, mildly ...

Studies of relativistic jets in active galactic nuclei with SKA

, 2014
Relativistic jets in active galactic nuclei (AGN) are among the most powerful astrophysical objects discovered to date. Indeed, jetted AGN studies have been considered a prominent science case for SKA, and were included in several different chapters of ...

The different flavors of extragalactic jets: Magnetized relativistic flows

We performed three-dimensional numerical simulations of magnetized relativistic jets propagating in a uniform density environment in order to study the effect of the entrainment and the consequent deceleration, extending a previous work in which magnetic

Magnetic acceleration of relativistic jets

, 2011
This is a brief review of the recent developments in the theory of magnetic acceleration of relativistic jets. We attempt to explain the key results of this complex theory using basic physical arguments and simple calculations.
