Abstract / Description of output
This paper presents a new grid-based method for investigating the
evolution of the steep-spectrum radio luminosity function, with the aim
of quantifying the high-redshift cut-off suggested by previous work. To
achieve this, the Combined EIS-NVSS Survey of Radio Sources (CENSORS)
has been developed; this is a 1.4-GHz radio survey, containing 135
sources complete to a flux density of 7.2mJy, selected from the NRAO VLA
Sky Survey (NVSS) over 6deg2 of the ESO Imaging Survey Patch
D (EISD). The sample is currently 7% spectroscopically complete, with
the remaining redshifts estimated via the K-z or I-z magnitude-redshift
relation. CENSORS is combined with additional radio data from the Parkes
All-Sky, Parkes Selected Regions, Hercules and Very Large Array (VLA)
COSMOS samples to provide comprehensive coverage of the radio power
versus redshift plane. The redshift distributions of these samples,
together with radio source count determinations, and measurements of the
local luminosity function, provide the input to the fitting process.
