Unified Scenario Study of Fanaroff−Riley Galaxy and Blazar

The Astrophysical Journal
Radio galaxies have two subclasses: Fanaroff−Riley type I (FR I) and type II (FR II). Within the radio-loud active galactic nucleus unification framework, FR I galaxies are considered to be the misaligned counterparts of BL Lacertae (BL Lac) objects ...

The ultra low-frequency spectral properties of bright extended radio galaxies in the 3CRR catalogue

Astronomy & Astrophysics
Context. Active galactic nuclei (AGN) jets are fundamental drivers of galaxy evolution, injecting kinetic energy into their environments. The large-scale morphology and spectral properties of these radio galaxies are consequences of complex particle ...

Energy Spectrum and Mass Composition of Ultra-high-energy Cosmic Rays Originating from Relativistic Jets of Nearby Radio Galaxies

The Astrophysical Journal
Relativistic jets of radio galaxies (RGs) are possible sources of ultra-high-energy cosmic rays (UHECRs). Recent studies combining relativistic hydrodynamic simulations with Monte Carlo particle transport have demonstrated that UHECRs can be accelerated ...

Jets in Fanaroff-Riley class I radio galaxies

, 1997
Presented here are observations, analysis and interpretation of five Fanaroff-Riley class I radio galaxies. Total intensity and polarised emission was observed in each source at 6 and 3 cm at angular resolutions of 16 to 2 arc seconds. These sources have

Hybrid Morphology Radio Sources from the MeerKAT Absorption Line Survey (MALS): Radio, Mid-infrared, and Environmental Characteristics

The Astrophysical Journal
Hybrid morphology radio sources (HyMoRSs) are a rare subclass of radio galaxies that display a Fanaroff–Riley type I (FR I) morphology on one side of the central supermassive black hole and a type II (FR II) morphology on the other.

Two-component Jets and the Fanaroff–Riley Dichotomy [PDF]

, 2011
The two types of Fanaroff–Riley radio loud galaxies, FRI and FRII, exhibit strong jets but with different properties. These differences may be associated to the central engine and/or the external medium.

Discovery of Giant Radio Sources from TGSS Alternative Data Release 1: Radio, Optical, and Infrared Properties

The Astrophysical Journal Supplement Series
Giant radio sources (GRSs) are the single largest astrophysical objects known in the Universe that have grown to megaparsec scales (≥0.7 Mpc). GRSs are much rarer compared with normal-sized radio galaxies.

Double-double radio galaxies: Further insights into the formation of the radio structures [PDF]

, 2010
Double-double radio galaxies (DDRGs) offer a unique opportunity for us to study multiple episodes of jet activity in large-scale radio sources. We use radio data from the Very Large Array and the literature to model two DDRGs, B1450+333 and B1834+620, in

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Are radio galaxies and quiescent galaxies different? Results from the analysis of HST brightness profiles

, 2005
We present a study of the optical brightness profiles of early type galaxies, using a number of samples of radio galaxies and optically selected elliptical galaxies. For the radio galaxy samples – B2 of Fanaroff-Riley type I and 3C of Fanaroff-Riley type
