Emission line imaging of 3CR quasars and radio galaxies

, 1996
Optical emission line images and spectra of sixteen 3CR powerful radio galaxies and quasars are presented. Extended line emission is detected in both radio galaxies and quasars.

The properties of FR0 radio galaxies as intermediate objects in the evolution of radio galaxies

The counter-rotation between black holes and accretion disk configuration was introduced over a decade ago to elucidate the nature of the radio loud/radio-quiet dichotomy and the jet-disk connection, but has since been applied to a plethora of ...

The angular power spectrum of NVSS radio galaxies

, 2004
We measure the angular power spectrum of radio galaxies in the NRAO VLA Sky Survey (NVSS) using two independent methods: direct spherical harmonic analysis and maximum likelihood estimation.

Bright radio galaxies with BeppoSAX

, 1999
Although a strong similarity between radio galaxies and Seyferts has been pointed out with ASCA, some radio galaxies do not seem to fit very well the cold thin accretion disk model proposed for radio quiet AGN.

Radio-only and Radio-to-far-ultraviolet Spectral Energy Distribution Modeling of 14 ULIRGs: Insights into the Global Properties of Infrared Bright Galaxies

The Astrophysical Journal
We present detailed spectral energy distribution (SED) modeling of 14 local ultraluminous infrared galaxies (ULIRGs) with outstanding photometric data from the literature covering the ultraviolet–infrared (FIR) and radio bands (∼50 MHz to ∼30 GHz).

Spitzer spectroscopy of 3C radio galaxies and quasars

, 2006
We are conducting a large survey of Fanaroff-Riley class II radio galaxies and quasars at redshift z < 1 with the Spitzer Infrared Spectrograph. The goal is to determine which radio galaxies contain hidden active nuclei with luminosities comparable to ...

Dynamical friction of radio galaxies in galaxy clusters

, 2008
Restricted Access. An open-access version is available at arXiv.org (one of the alternative locations)The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region.

The life cycles of radio galaxies

The life cycles of radio galaxies. Powerful radio galaxies are triggered when a supermassive black hole is fed by infalling gas, and represent a spectacular but transient phase in the life of a galaxy.

Radio galaxies in simba: a MIGHTEE comparison

We present a qualitative comparison between the host and black hole properties of radio galaxies in the MeerKAT GigaHertz Tiered Extragalactic Exploration~(MIGHTEE) survey with the radio galaxy population in the SIMBA suite of cosmological hydrodynamical
