Synchrotron polarization at the black hole horizon follows a universal pattern set solely by spin and inclination.
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*.
Simulations of VLBI networks including SKA-Mid in AA* and AA4 configurations predict 2x better size constraints, 4-30x improved Declination localization, and 3x better off-axis proper-motion detection for GRBs, extending measurable events to z approximately 0.25.
GRRT simulations show that raising the dilaton parameter shrinks the bright ring while increasing its width and brightness, disk thickness reduces diameter and width with weaker brightness impact, and both affect allowed ranges versus EHT Sgr A* data and the polarization coefficient beta2.
