In this chapter, we review some features of particle acceleration in astrophysical jets. We
begin by describing four observational results relating to the topic, with particular emphasis …

This article reviews the recent observational results regarding γ-ray emission from active
galaxies. The most numerous discrete extragalactic γ-ray sources are AGNs dominated by …

We describe the parsec-scale kinematics of 200 active galactic nucleus (AGN) jets based on
15 GHz Very Long Baseline Array (VLBA) data obtained between 1994 August 31 and 2011 …

The formation and large-scale propagation of Poynting-dominated jets produced by
accreting, rapidly rotating black hole systems are studied by numerically integrating the …

We investigate how the total radio luminosity of AGN-powered radio sources depends on
their accretion luminosity and the central black hole mass. Our studies cover about 7 orders …

We estimate the power of relativistic, extragalactic jets by modelling the spectral energy
distribution of a large number of blazars. We adopt a simple one-zone, homogeneous …

We present numerical simulations of axisymmetric, magnetically driven relativistic jets. Our
special-relativistic, ideal-magnetohydrodynamics numerical scheme is specifically designed …

Many luminous blazars which are associated with quasar-type active galactic nuclei display
broadband spectra characterized by a large luminosity ratio of their high-energy (γ-ray) and …

Blazars are the most violent steady/recurrent sources of high-energy gamma-ray emission in
the known Universe. They are prominent emitters of electromagnetic radiation throughout …

We investigate shock structure and particle acceleration in relativistic magnetized
collisionless pair shocks by means of 2.5 D and 3D particle-in-cell simulations. We explore a …
