A Chimera accretion flow can sustain MAD-level horizon flux and electromagnetic jet power without the standard MAD's eruptive variability, mass-flow geometry, or inner-disk morphology, so MAD-like behavior is multi-diagnostic and history-dependent.

Larger black holes in TDEs accrete more material and launch faster winds, with unbound mildly relativistic winds for higher viscosity parameters and bound convective outflows for lower ones.
GRMHD models show PA1 aligns with the approaching limb for high spins, enabling mild disfavoring of low spins and strong disfavoring of Earth-pointing spins in M87* from EHT data, with similar potential for Sgr A*.
GRMHD simulations identify magnetic flux through the black hole horizon as the key variable setting jet efficiency and radiative output across MAD, INT, and SANE states, with mappings to temporal classes in GRS 1915+105 and other sources.
Under fixed-background GRMHD and polarized radiative transfer, modified Kerr-Hayward black holes produce EHT fluid and image observables functionally indistinguishable from Kerr.
GRMHD simulations at spins 0.9375 and 0.998 yield similar fluid properties and full-Stokes EHT images, indicating prior lower-spin runs remain representative for a ≳ 0.9375.
