Simulated ring-like source with constant vertical EVPA using EHT 2017 array. Left panel: ground truth. Right panel: Preferred image (solution) recovered with MOEA/D image. Bottom row: super-resolved structures. Bottom row: images convolved with 20 µas beam shown in white. Vertical lines represent the EVPA and their color is the level of the polarization fraction. The color map for the brightness of the source is different to the one of the EVPAs.
