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 …

Radio-loud compact radio sources (CRSs) are characterised by morphological compactness
of the jet structure centred on the active nucleus of the galaxy. Most of the local elliptical …

Source classifications, stellar masses, and star-formation rates are presented for≈ 80 000
radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey …

Quasar feedback in the form of powerful outflows is invoked as a key mechanism to quench
star formation in galaxies, although direct observational evidence is still scarce and debated …

Context. Outflows accelerated by active galactic nuclei (AGN) are commonly observed in the
form of coherent, mildly collimated high-velocity gas directed along the AGN ionisation …

We present CO (2− 1) and adjacent continuum observations of seven nearby radio-quiet
type-2 quasars (QSO2s) obtained with ALMA at∼ 0.2 ″resolution (370 pc at z∼ 0.1). These …

Context. The z∼ 0.1 type-2 QSO J1430+ 1339, known as the “Teacup”, is a complex galaxy
showing a loop of ionised gas∼ 10 kpc in diameter, co-spatial radio bubbles, a compact (∼ …

We have performed a search over 3440 deg 2 of Epoch 1 (2017–2019) of the Very Large
Array Sky Survey to identify unobscured quasars in the optical (0.2< z< 3.2) and obscured …

Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and
radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical …

We analyse Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2
quasar (QSO2) SDSS J094521. 33+ 173753.2 to investigate its warm molecular and ionized …
