Mid-infrared selection of quasar-2s in Spitzer's First Look Survey
M. Lacy, G. Canalizo, S. Rawlings +6
We present early results from the spectroscopic follow-up of a sample of candidate obscured AGN selected in the mid-infrared from the Spitzer First Look Survey. Our selection allow…
The TexOx Survey of Radio-Selected Galaxy Clusters
Steve Croft, Steve Rawlings, Gary J. Hill +2
We present some initial results from the TexOx (Texas-Oxford) Cluster (TOC) survey - a new method of selecting distant galaxy clusters. The cosmic evolution of the radio source pop…
Extremely red radio galaxies
Chris J. Willott, Steve Rawlings, Katherine M. Blundell
At least half the radio galaxies at z>1 in the 7C Redshift Survey have extremely red colours (R-K>5), consistent with stellar populations which formed at high redshift (z>5). We di…
The radio galaxy K-z relation to z ~ 4.5
Matt J. Jarvis, Steve Rawlings, Steve Eales +2
Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K-z relation to z~4.5. The 6C* K-z dat…
Cosmological Studies from Radio Source Samples
Steve Rawlings
I review some recent cosmological studies based on redshift surveys of radio sources selected at low frequencies. The accretion rate onto the central black hole is identified as th…
No evidence for a `redshift cut-off' for the most powerful classical double radio sources
Matt J. Jarvis, Steve Rawlings, Chris J. Willott +3
We use three samples (3CRR, 6CE and 6C*) to investigate the radio luminosity function (RLF) for the `most powerful' low-frequency selected radio sources. We find that the data are…
