Numerical study of thin accretion disk images shows that increasing parity-odd scalar hair on Kerr black holes shrinks and distorts the photon ring and shadow, producing multiple disconnected shadows and chaotic lensing features in strong-hair regimes.
Kerr-BR black hole images with magnetically coupled synchrotron emissivity show spin- and B-dependent shifts in the inner disk edge, altered lensing rings, and Doppler asymmetries, with retrograde cases displaying wider central depletion.
Numerical backward ray-tracing shows that the inner shadow size shrinks with the Gauss-Bonnet coupling while polarization direction near the shadow and photon ring shifts noticeably, and combining both observables yields stronger constraints than either alone.
