Journal ArticleDOI
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,Clive Tadhunter,David Axon,R. Morganti,A. Robinson,M. B. N. Kouwenhoven,H. W. W. Spoon,Preeti Kharb,Katherine J. Inskip,J. Holt,C. Ramos Almeida,Nicole P. H. Nesvadba +11 more
TL;DR: In this paper, the authors presented deep Spitzer/IRS spectra for complete samples of 46 2Jy radio galaxies (0.05 75%) than their more extended counterparts and discussed this result in the context of a possible bias towards the selection of compact radio sources triggered in gas-rich environments.
Journal ArticleDOI
The environments of luminous radio galaxies and type-2 quasars
C. Ramos Almeida,C. Ramos Almeida,P. S. Bessiere,Clive Tadhunter,Katherine J. Inskip,Raffaella Morganti,D. Dicken,José Ignacio González-Serrano,J. Holt +8 more
TL;DR: In this article, the role of the environment in the triggering of powerful radio-loud and radio-quiet quasars was discussed based on the results of a comparison between the environments of (1) a complete sample of 46 southern 2-Jy radio galaxies at intermediate redshifts (0.05
Journal ArticleDOI
The origin of dust in early-type galaxies and implications for accretion onto supermassive black holes
TL;DR: In this paper, the authors conducted an archival Spitzer study of 38 early-type galaxies in order to determine the origin of the dust in approximately half of this population, and they used the Spitzer data to estimate dust masses, or establish upper limits, and found that all of the earlytype galaxies with dust lanes in the HST data are detected in all of Spitzer bands and have dust masses of approximately 10{sup 5}-10{sup 6.5} M{sub Sun }, while galaxies without dust lanes are not detected at 70 {mu}m
Journal ArticleDOI
Very Large Baseline Array observations of Mrk 6: probing the jet-lobe connection
Preeti Kharb,Christopher P. O'Dea,Stefi A. Baum,Martin J. Hardcastle,D. Dicken,Judith H. Croston,Beatriz Mingo,Beatriz Mingo,Jacob Noel-Storr +8 more
TL;DR: In this article, high-resolution VLBI (very long baseline interferometry) observations at 1.6 and 4.9 GHz of the radio-loud Seyfert galaxy, Mrk 6, are presented.
Journal ArticleDOI
The origin of the infrared emission in radio galaxies I: new mid- to far-infrared and radio observations of the 2Jy sample
TL;DR: In this article, the authors used the Spitzer Space Telescope to perform MIPS observations at the wavelengths of 24, 70 and 160 microns, detecting 100% of the sample at 24 microns and 90% at 70 microns.
