The unification model for powerful radio galaxies (RGs) and radio-loud quasars postulates that these objects are intrinsically the same but viewed along different angles. Herschel Space Observatory data permit the assessment of that model in the far-infrared spectral window. We analyze photometry from Spitzer and Herschel for the distant 3CR hosts, and find that RGs and quasars have different mid-infrared, but indistinguishable far-infrared colors. Both these properties, the former being…

Star formation in 3CR radio galaxies and quasars at z < 1
Using the Herschel Space Observatory we have observed a representative sample of 87 powerful 3CR sources at redshift z < 1. The far-infrared (FIR, 70-500 micron) photometry is combined with
The radio emission from active galactic nuclei
Context. For nearly seven decades astronomers have been studying active galaxies, that is to say galaxies with actively accreting central supermassive black holes, AGN. A small fraction of these are
A robust derivation of the tight relationship of radio core dominance to inclination angle in high redshift 3CRR sources
It is believed that, in radio-loud active galactic nuclei (AGN), the core radio flux density can be normalized to the flux density of the extended lobe emission to infer the orientation of a radio
Composite Spectral Energy Distributions and Infrared-Optical Colors of Type 1 and Type 2 Quasars
We present observed mid-infrared and optical colors and composite spectral energy distributions (SEDs) of type 1 (broad-line) and 2 (narrow-line) quasars selected from Sloan Digital Sky Survey (SDSS)
Starbursts and dusty tori in distant 3CR radio galaxies

Nowhere to hide: Radio-faint AGN in the GOODS-N field
Obtaining a census of active galactic nuclei (AGN) activity across cosmic time is critical to our understanding of galaxy evolution and formation. Many AGN classification techniques are compromised

Dust emission from 3C radio galaxies and quasars: New ISO observations favour the unified scheme
In order to test the unied scheme for luminous radio galaxies and quasars we observed 10 galaxy/quasar pairs from the 3CR catalogue with ISOPHOT at infrared wavelengths between 5 and 180 m. Each pair
Evidence against the unified scheme for powerful radio galaxies and quasars
It is shown that the currently popular unified scheme, in which the observed differences in the radio properties of powerful radio galaxies and steep-spectrum quasars are considered to arise merely
Spitzer Observations of 3C Quasars and Radio Galaxies: Mid-Infrared Properties of Powerful Radio Sources
We have measured mid-infrared radiation from an orientation-unbiased sample of 3CRR galaxies and quasars at redshifts 0.4 ≤ z ≤ 1.2 with the IRS and MIPS instruments on Spitzer. Powerful emission
The dust masses of powerful radio galaxies: clues to the triggering of their activity
We use deep Herschel Space Observatory observations of a 90 per cent complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 <z <0.7) with strong emission lines to estimate the dust
Near- and Mid-Infrared Photometry of High-Redshift 3CR Sources
Using the Spitzer Space Telescope, we have obtained 3.6-24 μm photometry of 38 radio galaxies and 24 quasars from the 3CR (Third Cambridge Revised Catalog of Radio Sources) at redshift 1 < z < 2.5.
We present a Spitzer mid-infrared survey of 42 Fanaroff-Riley class II radio galaxies and quasars from the 3CRR catalog at redshift z 8 × 10 to the 43rd ergs s^-1, indicating strong thermal emission

Unified models for active galactic nuclei and quasars
Because the critical central regions of Active Galactic Nuclei (AGN) and quasars are strongly nonspherical but spatially unresolved, orientation effects have been the source of much confusion. In
