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

Discovery of a Fanaroff–Riley type 0 radio galaxy emitting at γ-ray energies [PDF]
We present supporting evidence for the first association of a Fermi source, 3FGLJ1330.0-3818, with the FR0 radio galaxy Tol1326-379. FR0s represent the majority of the local radio loud AGN population but their nature is still unclear. They share the same properties of FRIs from the point of view of the nuclear and host properties, but they show a large

On the population of remnant Fanaroff–Riley type II radio galaxies and implications for radio source dynamics [PDF]
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 remnant FRII radio galaxies to confront models of remnant lobe evolution, and to provide guidance for ...

Multiwavelength Observations of the Second-Largest Known Fanaroff-Riley Type II Radio Galaxy, NVSS 2146+82 [PDF]
We present multifrequency VLA observations, multicolor CCD imaging, optical spectroscopy, and ROSAT HRI observations of the giant FR II radio galaxy NVSS 2146+82. This galaxy, which was discovered by the NRAO VLA Sky Survey, has an angular extent of nearly 20' from lobe to lobe.

The 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

On the relation between Fanaroff-Riley types I and II radio galaxies
Recent optical observations of radio galaxies reveal a transition from F-R II morphology to F-R I morphology with increasing optical luminosity at fixed radio luminosity. This transition can occur if a highly supersonic jet which normally fuels F-R II sources is instead strongly decelerated near the nucleus, producing the transonic or subsonic flow ...

Why Are Some Radio Galaxies Detected by Fermi, but Others Not?
Aiming to answer an interesting question on why some radio sources can be detected by Fermi-LAT but others cannot, we compare several parameters of Fermi-detected Fanaroff-Riley radio galaxies (FFRs) and non-Fermi-detected sources (NFFRs), including the ...
