Lensing configuration of lensed sources galaxies with different positions of SMBH mass. The 0.3 arcsec radius cyan circle locate the wandering SMBH. The blue curves are the caustics and the red curves the critical curve. The source is circular in the source plan is color-code with a simple gradient. The observed lensed image is located on the radial critical near the central galaxy of the cluster. Left: 1E8 Msol wandering SMBH positions close to the lensed sources. Right:1E9 Msol wandering SMBH positions further from the lensed sources. The x-axis locations is the same in each line. The y-axis locations for the left columns is higher for the effect of the SMBH to be seen. We can notice how the presence of the SMBH distort the image gradient. This would be visible either in a velocity field of the galaxy or potentially in a clumpy galaxy where the symmetry of the galaxy can easily be identified
