The first three images (from the left) show DES optical color images centered on the likely host galaxies of the three single ORCs (see Table 2 in Koribalski et al. 2021). The right two images made with SPLOTCH (Dolag et al. 2008) show the low-resolution simulation of the galaxy with galaxy formation physics on. The first shows the system at z ≈ 0.83, shortly before the first merger. The second shows the system at z ≈ 0.27, when the second shock has a size comparable to the observed diameter of the ORCs. Both are showing a region of 300 kpc in size.
