We were honored to attend an insightful seminar at Politecnico di Torino, led by Prof. Silvano Massaglia, coordinator of the Philofluid research group in the DISAT department. The session focused on normal and active galaxies, the Black Hole paradigm for active galaxies, and the fascinating world of Supermassive Black Holes (SMBH)—their locations, nature, detection methods, and formation.
