When the kinetic component is neglected [see panels (c) and (f) in Figure 6], accretion rates increase and persist over longer time-scales [∼103 kyr, see panel (c) Figure 7], and BHs grow significantly, reaching masses of 105−6 M⊙. This behaviour is consistent with other cosmologi- cal simulations (Prole et al. 2026; Chon et al. 2026) and isolated galaxy simulations (Toyouchi et al. 2021; Zana et al. 2026), in which feedback is purely radiative and accretion is modelled us- ing the BHL prescription.
