We show that the most distant X-ray-detected cluster known to date, Cl J1001 at ${z}_{\mathrm{spec}}=2.506$, hosts a strong overdensity of radio sources. Six of them are individually detected (within $10^{\prime\prime} $) in deep $0\buildrel{\prime\prime}\over{.} 75$ resolution VLA 3 GHz imaging, with ${S}_{3\mathrm{GHz}}\gt 8\,\mu...

Aims. We show how the XXL multiwavelength survey can be used to shed light on radio galaxies and their environment. Methods. Two prominent radio galaxies were identified in a visual examination of the mosaic of XXL-North obtained with the Giant Metrewave Radio Telescope at 610 MHz. Counterparts were searched for in other bands. Spectroscopic...
