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 ∼ 22.4 and K ∼ 20.6. An excess of galaxy counts in the K band is seen across these fields; these surplus galaxy counts are predominantly associated with red galaxies (R − K 4) of magnitudes 17.5 K 20.5 found within radial distances of ∼1 Mpc of the AGN host. These are exactly (though not uniquely) the… 
Galaxy protocluster candidates around z∼ 2.4 radio galaxies
We study the environments of six radio galaxies at 2.2 < z < 2.6 using wide-field near-infrared images. We use colour cuts to identify galaxies in this redshift range, and find that three of the
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.
MORPHOLOGIES IN A CLUSTER OF EXTREMELY RED GALAXIES WITH OLD STELLAR POPULATIONS AT z = 1.34
We have identified a clustering of red galaxies from deep optical/IR images obtained as part of the Institute for Astronomy Deep Survey. Photometric spectral energy distributions indicate that most
The environments of z ∼ 1 active galactic nuclei at 3.6 μm
We present an analysis of a large sample of active galactic nuclei (AGN) environments at z ~ 1 using stacked Spitzer data at 3.6 μm. The sample contains type 1 and type 2 AGN in the form of quasars
OVERDENSITIES OF EXTREMELY RED OBJECTS IN THE FIELDS OF HIGH-REDSHIFT RADIO-LOUD QUASARS
We have examined the occurrence of extremely red objects (EROs) in the fields of 13 luminous quasars (11 radio-loud and two radio-quiet) at 1.8 < z < 3.0. The average surface density of K_s ≤ 19 mag
Large scale structures around radio galaxies at z ~ 1.5
We explore the environments of two radio galaxies at z ~ 1.5, 7C 1751+6809 and 7C 1756+6520, using deep optical and near-infrared imaging. Our data cover 15 × 15 arcmin^2 fields around the radio
Spatial clustering of Ultra Steep Spectrum sources and galaxies
We present measurements of the clustering properties of galaxies in the field of redshift range 0.5 ≤ z ≤ 1.5 Ultra Steep Spectrum radio sources selected from the Sydney University Molonglo Sky
Protoclusters with evolved populations around radio galaxies at z∼ 2.5
We report the discovery of protocluster candidates around high-redshift radio galaxies at z ∼ 2.5 on the basis of clear statistical excess of colour-selected galaxies around them seen in the deep
An overdensity of extremely red objects around faint mid-IR galaxies
We have searched for Extremely Red Objects (EROs) around faint mid-IR selected galaxies in ELAIS fields. We find a significant overdensity, by factors of 2 to 5, of these EROs compared to field EROs
Protoclusters associated with distant radio galaxies
The results of a large program conducted with the Very Large Telescope and the Keck telescope to search for forming clusters of galaxies near powerful radio galaxies at 2 < z < 5.2 are presented.
