SFHs of simulated dwarf galaxies, within the virial radius (shaded histograms) and within 5 kpc of the centre (open histograms). Galaxies that evolved with AGN feedback are represented in blue, while those without AGNs are shown in green, and they are ordered according to their z = 0 BH mass (the most massive SMBH hosted in Halo 0, top left, the least massive one in Halo 11, bottom right). The logarithm of the SMBH accretion rate through time is indicated on the right-hand Y axis in each panel and is shown as a black line.
