Color image of the HFF galaxy cluster MACS J0416 shown in the main panel (red, green, and blue as F105W, F814W, and F606W, respectively). The MDLF centered in the north-east part of the cluster is outlined by the yellow contour (17.1 h integration time), while the blue contour shows the observation in the south-west (11 h integration, PI Bauer, 094.A-0525(A)). The red circles mark the positions of the 182 multiple images used to constrain the lens model (Bergamini et al. 2021). The insets show zoomed examples of strongly lensed objects with detected clumps in the redshift range of 1.5 <  z <  6.5 (discussed in detail in Sect. 4). In each inset, the catalog ID (red number) and redshift are indicated, while the segment marks the scale. Yellow circles mark two images not covered by MUSE, which are however included in the multiple images sample due to their mirroring lensing properties.
