Existence of Large Scale Synchrotron X-ray Jets in Radio-loud Active Galactic Nuclei [PDF]
In this paper, analytical arguments are presented that there exists a synchrotron X-ray jet on large scales in most radio-loud AGNs, based on the knowledge of the nature and physics of blazars. In blue blazars and blue-blazar-like radio galaxies, the large scale X-ray jet may get faint along the jet, while in most red blazars and red-blazar-like radio ...

X-Ray Emission Processes in Radio Jets [PDF]
The emission processes responsible for the observed X-rays from radio jets are commonly believed to be nonthermal, but in any particular case, it is unclear if synchrotron emission or one or more varieties of inverse Compton emission predominates.

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

AGN Jet Kinematics on Parsec-Scales: The MOJAVE Program
Very long baseline interferometry offers the best means of investigating the complex dynamics of relativistic jets powered by active galactic nuclei, via multi-epoch, sub-milliarcsecond, full-polarization imaging at radio wavelengths.

Acceleration of Ultra-high-energy Cosmic Rays in the Kiloparsec-scale Jets of Nearby Radio Galaxies
Radio galaxies have long been considered as potential sources of ultra-high-energy cosmic rays (UHECRs). Recent analyses of the UHECR spectrum, composition, and arrival directions indicate that the nearest radio galaxy, Centaurus A, could be linked to ...

FROM GALACTIC TO EXTRAGALACTIC JETS: A REVIEW
An analysis of the data that have recently become available from observing campaigns, including VLA, VLBA, and satellite instruments, shows some remarkable similarities and significant differences in the data from some epochs of galactic microquasars ...

Relativistic stellar jets: dynamics and non-thermal radiation
Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

Powers and Magnetization of Blazar Jets
In this work I review the observational constraints imposed on the energetics and magnetisation of quasar jets, in the context of theoretical expectations.
