Simulated Euclid observation in the I_E band of the central region of the strong lensing galaxy cluster MACSJ0416.1–2403 (z = 0.397, Balestra et al. 2016). The image was obtained with the code Hst2Euclid (Bergamini et al., in prep.), using HST observations taken as part of the Hubble Frontier Fields Survey (Lotz et al. 2017). The image reproduces the depth of the EWS and several giant arcs are clearly visible. The inset shows a zoom into a known galaxy-galaxy strong lensing system, where the lens is a cluster member and the source a background galaxy at redshift z = 3.222 (ID14, Vanzella et al. 2017b).
