Protocluster candidates in COSMOS and XMM-LSS fields (yellow swathes) with the areas we consider in this work highlighted by red boxes. The gray-scale background indicates the surface density of photometrically selected LAEs, with darker colors corresponding to higher values, as indicated by the color bar. The structures considered in V. Ramakrishnan et al. (2025b) are marked in blue, while a confirmed proto-supercluster, Hyperion (O. Cucciati et al. 2018) is marked in green.
