An analysis of the environments around a sample of 28 3CR radio galaxies with redshifts 0.6<z<1.8 is presented, based primarily upon K-band images down to K∼20 taken using the UK Infrared Telescope (UKIRT). A net overdensity of K-band galaxies is found in the fields of the radio galaxies, with the mean excess counts being comparable to that expected for clusters of Abell Class 0 richness. A sharp peak is found in the angular cross-correlation amplitude centred on the radio galaxies that, for… Expand
Red galaxy overdensities and the varied cluster environments of powerful radio sources with z~1.6
The environments of a complete subsample of six of the most powerful radio-loud active galactic nuclei (AGN) at redshifts z ∼ 1.6 are investigated, using deep RJK imaging to depths of R ∼ 26, J ∼Expand
Clustering around radio galaxies at z∼1.5
Abstract The importance of studying old elliptical galaxies at redshift z ∼1.5 is reviewed, considering both what can be learned by extending studies of the evolution of cluster galaxy scalingExpand
Clustering of Red Galaxies Around the z = 1.53 Quasar 3C 270.1
In the paradigm of hierarchical galaxy formation, luminous radio galaxies mark mass assembly peaks that should contain clusters of galaxies. Observations of the z = 1.53 quasar 3C 270.1 with theExpand
The environment of active objects in the nearby Universe
We study the galaxy environment of active galaxies, radio-loud and radio-quiet quasars in the redshift range 0.1 ≤ z ≤ 0.25. We use galaxies from the APM survey in order to explore the local galaxyExpand
NICMOS Observations of High-Redshift Radio Galaxies: Witnessing the Formation of Bright Elliptical Galaxies?
We present the results of a near-infrared imaging program of a sample of 19 radio galaxies with redshift between 1.7 and 3.2, using the NICMOS Camera 2 on the Hubble Space Telescope (HST). TheExpand
Clustering and Light Profiles of Galaxies in the Environment of 20 Ultra-Steep-Spectrum Radio Sources*
We have analyzed galaxy properties in the neighborhood of 20 ultra–steep-spectrum (USS) radio sources taken from the Westerbork in the Southern Hemisphere (WISH) catalog of De Breuck and coworkers.Expand
Galaxy Population in a Cluster of Galaxies around the Radio Galaxy 3C 324 at z = 1.2
We discuss the properties of galaxies around the radio galaxy 3C 324 at z =1 .2 based on BV RI Kmulti-band imaging data. We have applied a photometric-redshift technique to objects in the 3C 324Expand
The Ks-band luminosity and stellar mass functions of galaxies in z ∼ 1 clusters
We present the near-infrared (K s -band) luminosity function of galaxies in two z ∼ 1 cluster candidates, 3C 336 and Q1335+28. A third cluster, 3C 289, was observed but found to be contaminated by aExpand

We study the cluster environment for a sample of 21 radio loud AGN from the 3CR catalog at z>1, 12 radio galaxies and 9 quasars with HST images in the optical and IR. We use two different approachesExpand


HST, radio and infrared observations of 28 3CR radio galaxies at redshift z ∼ 1 — II. Old stellar populations in central cluster galaxies
Hubble Space Telescope images of 3CR radio galaxies at redshifts 0.6 < z < 1.8 have shown a remarkable variety of structures, generally aligned along the radio axis, indicating that the radio sourceExpand
