Spitzer mid-IR spectroscopy of powerful 2Jy and 3CRR radio galaxies. I. Evidence against a strong starburst-AGN connection in radio-loud AGN
D. Dicken, C. Tadhunter, D. Axon +9
We present deep Spitzer/IRS spectra for complete samples of 46 2Jy radio galaxies (0.05<z<0.7) and 19 3CRR FRII radio galaxies (z<0.1), and use the detection of polycyclic aromatic…
PKS 1814-637: a powerful radio-loud AGN in a disk galaxy
R. Morganti, J. Holt, C. Tadhunter +5
We present a detailed study of PKS1814-637, a rare case of powerful radio source (P_5 GHz = 4.1 x 10^25 W/Hz) hosted by a disk galaxy. Optical images have been used to model the ho…
Are luminous radio-loud active galactic nuclei triggered by galaxy interactions?
C. Ramos Almeida, P. S. Bessiere, C. Tadhunter +6
We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2Jy radio galaxies at intermediate redshifts (0.05<z<0.7) and those of t…
Clear detection of dusty torus signatures in a Weak-Line Radio Galaxy: the case of PKS 0043-42
Cristina Ramos Almeida, Daniel Dicken, Clive Tadhunter +4
We report the clearest detection to date of dusty torus signatures in a Weak-Line Radio Galaxy (WLRG). The deep Spitzer InfraRed Spectrograph (IRS) rest-frame mid-infrared (MIR) sp…
