Abstract
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 data significantly improve delineation of the K-z relation for radio galaxies at high redshift (z > 2). In a spatially flat universe with a cosmological constant ( ΩM=0.3 and ΩΛ=0.7 ), the most luminous radio sources appear to be associated with galaxies with a luminosity distribution with a high mean ( ≈5L∗ ), and a low dispersion ( σ∼0.5 mag) which formed their stars at epochs corresponding to z≳2.5 ).
