Parameter space of the SMBH accretion disk in the ﹩(\dot{M}/\alpha ,{M}_{\bullet })﹩ plane. Red indicates a regime of dynamical starburst where luminous mass >M_• is needed to support L_disk (Equation (12)), while the gray region marks the transition to a non-self-gravitating AGN disk (Equation (14)). These regimes may reflect sequential stages of SMBH disk evolution, transitioning from LRD-like systems to standard AGN disks.
