Extremely Red Radio Galaxies
At least half the radio galaxies at z > 1 in the 7C Redshift Survey have extremely red colours (R−K > 5), consistent with stellar populations which formed at high redshift (z ∼ 5). We discuss the implications of this for the evolution of massive galaxies in general and for the fraction of near-IR-selected EROs which host AGN, a result which is now being tested by deep, hard X-ray surveys. The c...
متن کاملNicmos Imaging of High-redshift Radio Galaxies
We have obtained near–infrared (1.6 µm) images of 11 powerful 3CR radio galaxies at redshifts 0.8 < z < 1.8 using NICMOS on board HST. The high angular resolution permits a detailed study of galaxy morphology in these systems at rest–frame optical wavelengths, where starlight dominates over the extended, aligned UV continuum. The NICMOS morphologies are mostly symmetric and are consistent with ...
متن کاملHigh-redshift radio galaxies: at the crossroads
The next generation of surveys of extragalactic radio sources will be dominated by different types of objects than the jetted-AGN that dominate surveys like 3C, 6C and 7C. Before radio astronomy becomes concentrated on the new types of object, it is vital that we understand the cosmological importance of the jetted-AGN that have been studied for many years. I argue that, as observational manife...
متن کاملHigh Redshift Css Radio Galaxies
We discuss CSS radio galaxies from 2 samples of radio sources. The rst sample is a complete sample of 28 3CR galaxies with redshifts in the range 0:6 < z < 1:8 for which we have HST, UKIRT and VLA imaging data. The 2 CSS galaxies contained in this sample, 3C49 and 3C241, appear to be less active than galaxies with radio sizes of order 50{100 kpc, but similar in activity to galaxies with radio s...
متن کاملVery High Redshift Radio Galaxies
High redshift radio galaxies (HzRGs) provide unique targets for the study of the formation and evolution of massive galaxies and galaxy clusters at very high redshifts. We discuss how efficient HzRG samples are selected, the evidence for strong morphological evolution at near-infrared wavelengths, and for jet-induced star formation in the z = 3.800 HzRG 4C41.17.
