Extended Data Fig. 1: Stellar mass functions of the SIMBA, EAGLE, and TNG simulation variants compared with GAMA.
From: Galaxy and black hole co-evolution in dark matter haloes not captured by cosmological simulations
Panels are grouped by simulation (snapshots at z ≈ 0.1) and, for each simulation, show the stellar mass functions of the global, high-SFR, low-SFR, and quiescent populations, defined by ΔSFR relative to the star-forming main sequence (SFMS). In all panels, the violet curves show the median stellar mass function and the 16th–84th percentile uncertainty range derived from fits to GAMA galaxies at z < 0.12. Error bars on the simulation curves indicate standard deviations assuming Poisson statistics. SIMBA (a-d): Black, red, green, and blue curves correspond to SIMBA variants with X-ray feedback disabled; both jet-mode and X-ray AGN feedback disabled; all AGN feedback disabled; and all AGN and supernova feedback processes disabled, respectively. EAGLE (e-h): Red, teal, green, and blue curves correspond to the fiducial EAGLE-50 simulation; the EAGLE-50 variant with increased AGN heating temperature (TAGN = 109 K); the EAGLE-50 simulation with AGN feedback disabled; and the higher-resolution EAGLE-25 simulation, respectively. TNG (i-l): Blue, green, and red curves show the three volume variants of the TNG simulations.
