English: "Second, the simulations use very large numbers of particles, up to 3 × 1011, which is the largest number of resolution elements for any existing cosmological hydrodynamical simulation run to z = 0. See Fig. 2 for a comparison with simulations from the literature." "Comparison of the resolutions (baryonic particle mass or target cell mass; resolution increases along the y-axis) and box sizes of the FLAMINGO runs (filled red circles) with cosmological, hydrodynamical simulations from the literature that include radiative cooling, use a box size of at least (100 Mpc)3, and were run down to z = 0. The grey diagonal lines indicate the total number of baryonic resolution elements. The simulations from the literature shown are BAHAMAS (McCarthy et al. 2017), cosmo-OWLS (Le Brun et al. 2014), EAGLE (Schaye et al. 2015), Horizon-AGN (Dubois et al. 2014), IllustrisTNG (Springel et al. 2018), Magneticum (Dolag et al. 2016), MassiveBlack-II (Khandai et al. 2015), MillenniumTNG (Pakmor et al. 2022), OWLS (Schaye et al. 2010), SIMBA (Davé et al. 2019), and SLOW (Dolag et al. 2023)."
