Simulated convergence maps of a cluster lens, namely with ID = 4, at z_l = 0.22 and considering z_s = 3, obtained by collapsing the total mass along the z-projection. The left and the central panels show the results using two different hydro-solvers GadgetX and GIZMO-SIMBA, respectively. In the right panel, we display the convergence map of the same cluster projection simulated using only collisionless dark matter particles, DM-only run. The assumed field of view is 5 Mpc by side, collapsing ±5 Mpc matter along the line-of-sight.
