Radio Galaxy Zoo: A Search for Hybrid Morphology Radio Galaxies [PDF]

, 2017
Hybrid morphology radio sources (HyMoRS) are a rare type of radio galaxy that display different Fanaroff-Riley classes on opposite sides of their nuclei.

UNDERSTANDING THE FANAROFF–RILEY RADIO GALAXY CLASSIFICATION [PDF]

The Astronomical Journal, 2012
The simple, yet profoundly far-reaching classification scheme based on extended radio morphologies of radio galaxies, the Fanaroff-Riley classification has been a cornerstone in our understanding of radio galaxies. Over the decades since the recognition that there are two basic types of radio galaxy morphologies there have been several findings in ...

Relativistic Jets and the Fanaroff-Riley Classification of Radio Galaxies [PDF]

The Astrophysical Journal Supplement Series, 1995
Recently, Owen(1993) and Owen and Ledlow (1994) have shown that the dividing line between Fanaroff-Riley class~I and class~II Radio Sources is very sharp when the sources are represented as points in the radio-optical luminosity plane. It is shown that if one accepts the propositions that the sources in the vicinity of this dividing line are ...

The nature of compact radio sources: the case of FR0 radio galaxies [PDF]

, 2023
Radio-loud compact radio sources (CRSs) are characterised by morphological compactness of the jet structure centred on the active nucleus of the galaxy.

On the Encounter between the GASP Galaxy JO36 and the Radio Plume of GIN 049

The Astrophysical Journal, 2023
We report the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observations at 144 MHz of the galaxy cluster A160 ( z = 0.04317) provided by the ...

The particle content of low-power radio galaxies in groups and clusters [PDF]

, 2013
The synchrotron-radiating particles and magnetic fields in low-power radio galaxies (including most nearby cluster-centre sources), if at equipartition, can provide only a small fraction of the total internal energy density of the radio lobes or plumes ...

A Simulation Study of Ultra-relativistic Jets. III. Particle Acceleration in FR-II Jets

The Astrophysical Journal, 2023
We study the acceleration of ultra-high-energy cosmic rays (UHECRs) in Class II Fanaroff–Riley (FR-II) radio galaxies by performing Monte Carlo simulations for the transport, scattering, and energy change of CR particles injected into time-evolving jet ...

Shock heating by Fanaroff–Riley type I radio sources in galaxy clusters [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2007
Abstract Feedback by active galactic nuclei (AGN) is frequently invoked to explain the cut-off of the galaxy luminosity function at the bright end and the absence of cooling flows in galaxy clusters. Meanwhile, there are recent observations of shock fronts around radio-loud AGN. Using realistic 3D simulations of jets in a galaxy cluster,

Effects of large-scale AGN feedback in local galaxies

, 2012
The effects of active galactic nucleus (AGN) feedback on group and cluster galaxies are investigated. We examine the colors of non-AGN hosts (i.e. satellite galaxies) by comparing galaxies overrun by radio AGN with similar galaxies located outside the ...

Multiple Shock Fronts in RBS 797: The Chandra Window on Shock Heating in Galaxy Clusters

The Astrophysical Journal, 2023
Using ∼427 ks of Chandra observations, we present a study of shock heating and intracluster medium (ICM) cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roughly 50, 80, and 130 kpc from the center. The total energy
