Steady GRMHD jets exhibit a universal near-horizon polarization pattern set only by black hole spin, with large-radius polarization angle following a collimation-determined power law and intermediate scales modified by plasma loading.
Synthetic EHT data from semi-analytic jet models show that the 2022 array configuration enables robust recovery of faint horizon-scale jet emission in M87* when jet intensity exceeds a determined lower limit.
The work proposes GRMHD jet simulations to generate synthetic synchrotron maps and polarization signatures for testing physical models of observed magnetic filaments.
