The 6** sample and the highest redshift radio galaxies
Cruz, M.J.; Jarvis, M.J.; Blundell, K.M.; Rawlings, S. (World Scientific Publishing, 2004)We present a new radio sample, 6C** designed to find radio galaxies at z > 4 and discuss some of its near-infrared imaging follow-up results. -
The 6C** sample of steep-spectrum radio sources: I - Radio data, near-infrared imaging and optical spectroscopy
Cruz, M.J.; Jarvis, M.J.; Blundell, K.M.; Rawlings, S.; Croft, S.; Kloeckner, H-R.; McLure, R.J.; Simpson, C.; Targett, T.A.; Willott, C.J. (2006)We present basic observational data on the 6C** sample. This is a new sample of radio sources drawn from the 151MHz 6C survey, which was filtered with radio criteria chosen to optimize the chances of finding radio galaxies ... -
The 6C** sample of steep-spectrum radio sources: II - Redshift distribution and the space density of high-redshift radio galaxies
Cruz, M.J.; Jarvis, M.J.; Rawlings, S.; Blundell, K.M. (2007)We use the 6C** sample to investigate the co-moving space density of powerful, steep- spectrum radio sources. This sample, consisting of 68 objects, has virtually complete K-band photometry and spectroscopic redshifts for ... -
A doubled double hot spot in J0816+5003 and the logarithmic slope of the lensing potential
Blundell, K.M.; Schechter, P.L.; Morgan, N.D.; Jarvis, M.J.; Rawlings, S.; Tonry, J.L. (2010)We present an analysis of observations of the doubly lensed double hot spot in the giant radio galaxy J0816+5003 from MERLIN, MDM, WIYN, WHT, UKIRT, and the VLA. The images of the two hot spot components span a factor of ... -
Near-infrared imaging and the K-z relation for radio galaxies in the 7C redshift survey
Willott, C.J.; Rawlings, S.; Jarvis, M.J.; Blundell, K.M. (2003) -
On the redshift cut-off for steep-spectrum radio sources
Jarvis, M.J.; Rawlings, S.; Willott, C.J.; Blundell, K.M.; Eales, S.; Lacy, M. (2001) -
A sample of 6C radio sources designed to find objects at redshift z>4: II - spectrophotometry and emission line properties
Jarvis, M.J.; Rawlings, S.; Lacy, M.; Blundell, K.M.; Bunker, A.; Eales, S.; Saunders, R.; Spinrad, H.; Stern, D.; Willott, C.J. (2001) -
A sample of 6C radio sources designed to find objects at redshift z>4: III - imaging and the radio galaxy K-z relation
Jarvis, M.J.; Rawlings, S.; Eales, S.; Blundell, K.M.; Bunker, A.; Croft, S.; McLure, R.J.; Willott, C.J. (2001)
