Comparison of the zoomed-in images of one of the known satellites (left panel, dw1906m6357) shown in Fig. 15 and a galaxy (dw1912m6351, right panel) identified as a background object based on surface brightness fluctuation measurements by Carlsten et al. (2022). The sharp PSF of Euclid allows us to clearly see that the stellar population is resolved in the image on the left (satellite), but not in the image on the right (background galaxy). The images are 40ʺ on a side, with north up, and east to the left.
