Black holes (BH) are objects described by General Relativity (GR),particularly by the Kerr solution. However, this solution is based onsimplifying assumptions. To achieve a more realistic approach, we investigatethe impact of deviations from the Kerr solution on the imaging of supermassiveblack holes (SMBH). We conduct General Relativistic Radiation Transportsimulations using a Kerr-Like metric, which includes four nonlinear freedeviation functions and is stationary, axis-symmetric, and asymptotically flat.The RAPTOR I code, an open-source ray-tracing code capable of handlingarbitrary spacetimes, is employed to generate the images. We analyze theasymmetry, diameter, and shadow displacement of the BH to compare them withthose of a Kerr BH. Our findings confirm that these deviations significantlyaffect the shape of the shadow. However, we acknowledge the importance ofconsidering the matter distribution and emissivities surrounding the BH, as theresults cannot be solely inferred from the shape of the photon ring.

Exploring how deviations from the Kerr metric can affect SMBH images
