Galaxy clusters (shaded circles), superclusters, and polarized sources (crosses, with their RRM values as indicated in the color bar) in the ELAIS-N1 LOFAR Deep Field. The radii of the circles indicate r₂₀₀ of the clusters, except for the clusters that are located in superclusters, whose sizes are not known; we used an arbitrary diameter of 30′ for the plot (solid green circles). The shaded gray circles represent the clusters of Wen & Han (2024) and the shaded blue circles show the clusters from Zou et al. (2022). The dashed green ellipse and the circle represent the two superclusters from Chow-Martínez et al. (2014) in the field (Table 6). The shaded orange circles represent the clusters detected in X-rays from Böhringer et al. (2000) and/or the PSZ2 Planck Collaboration XXVII (2016) catalogs. The orange square represents the X-ray Sunyaev-Zel’dovich cluster candidate from Tarrío et al. (2019), for which no radius is available.
