Publications of the Astronomical Society of Australia, 2022 We study the radio power of the core and its relation to the optical properties of the host galaxy in samples of high excitation (HERG) and low excitation (LERG) Fanaroff-Riley type II (FRII) radio galaxies.

On the population of remnant Fanaroff-Riley type II radio galaxies and implications for radio source dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The purpose of this work is two-fold: (1) to quantify the occurrence of ultrasteep spectrum remnant Fanaroff-Riley type II (FRII) radio galaxies in a 74 MHz flux-limited sample, and (2) perform Monte Carlo simulations of the population of active and ...

Fundamental properties of Fanaroff-Riley type II radio galaxies investigated via Monte Carlo simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 Radio galaxies and quasars are among the largest and most powerful single objects known and are believed to have had a significant impact on the evolving Universe and its large-scale structure.

The γ-ray emission region in the Fanaroff-Riley II radio galaxy 3C111 [PDF]
The Astrophysical Journal, 2012 The broad-line radio galaxy 3C111, characterized by a Fanaroff-Riley II (FRII) radio morphology, is one of the sources of the misaligned active galactic nucleus sample, consisting of radio galaxies and steep spectrum radio quasars, recently detected by ...

The Astronomical JournalThe Fanaroff–Riley radio galaxies exhibit the most extensive radio emissions derived from the active nuclei of galaxies. They morphologically differ from the highly compact and bright radio galaxies observed as gigahertz peaked spectrum and compact steep

A physically-motivated perspective of the Fanaroff-Riley classification of radio galaxies
, 2023 A small subset of extragalactic double radio sources, termed HYMORS (HYbrid MOrpholgy Radio Sources), is distinguished by a very unusual, hybrid morphology in terms of the Fanaroff-Riley (FR) classification.

The twin-jet system in the Fanaroff-Riley II radio galaxy 3C 452
Astronomy & AstrophysicsAims. We present a comprehensive multifrequency VLBI analysis of the Fanaroff-Riley II (FRII) high-excitation radio galaxy 3C 452. Our aim is to resolve and analyze, for the first time, its twin-jet structure on sub-parsec scales. Methods.

Fanaroff–Riley dichotomy of radio galaxies and the Malmquist bias [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We examine the possibility that a claimed dependence of the FR 1/2 break value in radio luminosity on the absolute magnitude of the optical host galaxy could be due to the Malmquist bias, where a redshift-luminosity correlation appears in a flux-limited sample because of an observational selection effect.
