We study the prospect of Bardeen black holes in explaining the observedshadow of Sgr A* and M87*. Bardeen black holes are regular black holes endowedwith a magnetic monopole charge that arise in Einstein gravity coupled tonon-linear electrodynamics. These black holes are interesting as they can evadethe r = 0 curvature singularity arising in general relativity. It is thereforeworthwhile to look for signatures of Bardeen black holes in astrophysicalobservations. With two successive release of black hole images by the EventHorizon Telescope (EHT) collaboration, the scope to test the nature of stronggravity has substantially increased. We compare the theoretically computedshadow observables with the observed image of Sgr A* and M87*. Our analysisreveals that while the observed angular diameter of M87* favors the Kerrscenario, the shadow of Sgr A* can be better explained by the Bardeenbackground. This indicates that although rare, certain black holes exhibit apreference towards regular black holes like the Bardeen spacetime.

Do shadows of Sgr A* and M87* indicate black holes with a magnetic monopole charge?
