Its shadow, assuming no rotation, spans similar to 50 mu as. Resolving such dimensions has long been out of reach for astronomical instruments until a new generation of interferometers being operational during this decade. Of particular interest is the Event Horizon Telescope (EHT) with resolution similar to 20 mu as in the millimeter- wavelength range 0.87 mm - 1.3 mm. We investigate the ability of the fully general relativistic Komissarov (2006, MNRAS, 368, 993) analytical magnetized torus model to account for observable constraints at Sgr A* in the centimeter and millimeter domains. The impact ofthe magnetic field geometry on the observables is also studied. We show that the torus model is capable of reproducing spectral constraints in the millimeter domain, and in particular in the observable domain of the EHT. However, the tor ER -
