We review current understanding of the population of radio galaxies and radio-loud quasars
from an observational perspective, focusing on their large-scale structures and dynamics …

Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the
accretion of material onto a compact object. Despite this ubiquity, many fundamental physics …

After being launched, gamma-ray burst (GRB) jets propagate through dense media prior to
their breakout. The jet-medium interaction results in the formation of a complex structured …

Relativistic hydro and magnetohydrodynamics provide continuum fluid descriptions for gas
and plasma dynamics throughout the visible universe. We present an overview of state-of …

We have performed magnetohydrodynamic (MHD) simulations of relativistic jets from
supermassive blackholes over a few tens of kpc for a range of jet parameters. One of the …

The interaction of gamma-ray burst (GRB) jets with the dense media into which they are
launched promote the growth of local hydrodynamic instabilities along the jet boundary. In a …

Analysis is presented for 15 months of data taken with the Large Area Telescope (LAT) on
the Fermi Gamma-ray Space Telescope for 11 non-blazar active galactic nuclei (AGNs) …

The first neutron star binary merger detected in gravitational waves, GW170817, and the
subsequent detection of its emission across the electromagnetic spectrum showed that …

Relativistic magnetized jets are key elements in active galactic nuclei and in other
astrophysical environments. Their structure and evolution involve a complex non-linear …

Shear flows are ubiquitously present in space and astrophysical plasmas. This paper
highlights the central idea of the non-thermal acceleration of charged particles in shearing …
