Abstract / Description of output
The properties of the host galaxies of powerful 3CR radio galaxies at redshift z similar to 1 are investigated, using observations made with the HST and UKIRT. Out to radii r similar to 35 kpc their radial intensity profiles are well matched by de Vaucouleurs' law, but at larger radii they show an excess of emission very similar to that seen around nearby cD galaxies. The bright absolute magnitudes of these galaxies imply that they are amongst the most massive galaxies at their redshifts, whilst their large characteristic radii indicate that they are highly evolved dynamically. These results are supplemented by independent evidence to suggest that powerful distant radio galaxies provide unique probes of young, possibly forming, clusters at redshifts z greater than or equal to 1.
