X-ray images in the 0.5–2 keV energy range of the three high-z sources described in this paper obtained with the Swift-XRT telescope and smoothed with a Gaussian function with σ = 2 pixels (∼4.7″). The orange cross indicates the optical position of the QSO, while the contours are from the RACS-mid images and are drawn starting from ±5× off-source RMS and spaced by factors of $\sqrt{2}$.
