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 ... -
A large area search for radion-loud quasars within the epoch of reionization
Jarvis, M.J.; Rawlings, S.; Barrio, F.E.; Hill, G.J.; Bauer, A.; Croft, S. (2004) -
A large area search for radion-loud quasars within the epoch of reionization
Jarvis, M.J.; Rawlings, S.; Barrio, F.E.; Hill, G.J.; Bauer, A.; Croft, S. (World Scientific Publishing, 2004)The Universe became fully reionized, and observable optically, at a time corresponding to redshift z ~ 6.5, so it is only by studying the HI and molecular absorption lines against higher-redshift, radio-loud sources that ... -
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) -
A Search for Radio-loud Quasars within the Epoch of Reionization
Jarvis, M.J.; Rawlings, S.; Barrio, F.E.; Hill, G.J.; Bauer, A.; Croft, S. (Astronomical Society of the Pacific, 2004)The Universe became fully reionized, and observable optically, at a time corresponding to redshift z~6.5, so it is only by studying the HI and molecular absorption lines against higher-redshift, radio-loud sources that one ... -
A young, dusty, compact radio source within a Lyα halo
Barrio, F.E.; Jarvis, M.J.; Rawlings, S.; Bauer, A.; Croft, S.; Hill, G.J.; Manchado, A.; McLure, R.J.; Smith, Daniel; Targett, T.A. (2008)
