The evolution of radio galaxies

combination of three tests to remove radio galaxies where.. The bivariate luminosity distribution. The space density represented by a colour-scale in the optical

This thesis considers the possible evolution in the Far-Infrared - Radio Correlation (FIRC) of mainly low redshift ( z < 0. 5) galaxies, in terms of either redshift or

Owen & Laing (1989) and Owen & White (1991) have noted a segregation of FRI and FRII radio galaxies in the radio power to host optical luminosity plane, suggesting

Redshift distribution and luminosity function of long gamma-ray bursts from cosmological simulations.

I compare the results obtained for the high–redshift clusters with the nearby Coma cluster and show that high redshift clusters exhibit a deficit of low– luminosity galaxies on

However, a drawback of this work is that the sample was fundamentally limited by the degeneracy between redshift and luminosity in flux-density limited samples. 1 in order to

The study was done for a representative sample of radio sources, the nearby (redshift z < 0.5) 3CRR sources, and separately for samples of giant radio sources and X-shaped

(iii) Remnant sources, after the jet has switched off, show a rapid evolution of radio luminosity and spectral index due to the ces- sation of injection of new flat-spectrum
