RAdio Galaxy Environment Reference Survey
Listed in IVOA Registry (Virtual Observatory)
High-redshift radio(-loud) galaxies (HzRGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification.
Description
However, the interplay between HzRGs and the large-scale environment remains unclear. To understand the connection between HzRGs and the surrounding obscured star formation, we investigated the overdensity and spatial distribution of submillimeter-bright galaxies (SMGs) in the field of 4C 23.56, a well-known HzRG at z=2.48.
We used SCUBA-2 data ({sigma}~0.6mJy) to estimate the 850um source number counts and examine the radial and azimuthal overdensities of the 850um sources in the vicinity of the HzRG. The angular distribution of SMGs is inhomogeneous around the HzRG 4C 23.56, with fewer sources oriented along the radio jet. We also find a significant overdensity of bright SMGs (S_850um_>=5mJy).

Faint and bright SMGs exhibit different spatial distributions. The former are concentrated in the core region, while the latter prefer the outskirts of the HzRG field. High-resolution observations show that the seven brightest SMGs in our sample are intrinsically bright, suggesting that the overdensity of bright SMGs is less likely due to the source multiplicity.
