Super-Eddington accreting massive black holes as long-lived cosmological standards

J. -M. Wang, P. Du, D. Valls-Gabaud +2

Super-Eddington accreting massive black holes (SEAMBHs) reach saturated luminosities above a certain accretion rate due to photon trapping and advection in slim accretion disks. We…
