An analytical model for extragalactic radio sources with pressure-confined jets is presented.
We show that the properties of the bow shock and of the gas surrounding these objects force …

We present four Mpc-sized radio galaxies which consist of a pair of double-lobed radio
sources, aligned along the same axis, and with a coinciding radio core. We call these …

This is the second in a series of papers presenting an analytical model for the evolution of
FRII radio sources. In this paper we evaluate the expected radio emission from a radio …

Giant radio sources (GRSs) defined to be> 0.7 Mpc are the largest single objects in the
Universe and can be associated with both galaxies (GRGs) and quasars (GRQs). They are …

The radio sources in the galaxy cluster A3667 have been imaged using the Australia
Telescope Compact Array at both 13 and 20 cm. The most striking source is a large region …

Context. Giant radio galaxies (GRGs, or colloquially 'giants') are the Universe's largest
structures generated by individual galaxies. They comprise synchrotron-radiating active …

This paper describes an investigation of the early evolution of extragalactic radio sources
using samples of faint and bright gigahertz peaked spectrum (GPS) and compact steep …

Giant radio galaxies (GRGs) are a subclass of radio galaxies, which have grown to
megaparsec scales. GRGs are much rarer than normal-sized radio galaxies (< 0.7 Mpc) and …

In this article, I review past, current, and future advances on the study of radio-loud AGN
(RLAGN; radio-loud quasars and radio galaxies) lifecycles exclusively in the remnant and …

There has been a growing body of evidence to suggest that AGN activity, which is powered
by mass accretion on to a supermasive black hole, could be episodic, although the range of …
