Paradigms and scenarios for the dark matter phenomenon

Paolo Salucci



Well known scaling laws among the structural properties of the dark and the luminous matter in disc systems are too complex to have arisen by two inert components that just share the same gravitational field. This brings us to critically focus on the 30 year old paradigm, that, resting on a priori knowledge of the nature of dark matter (DM), has led us to a restricted number of scenarios, especially favouring the collisionless Cold Dark Matter one. Motivated by such observational evidence, we propose to resolve the dark matter mystery by following a new paradigm: the nature of DM must be guessed/derived by deeply analyzing the properties of the dark and luminous mass distribution at galactic scales. The immediate application of this paradigm leads us to the existence of a direct interaction between dark and Standard Model particles which has finely shaped the inner regions of galaxies.
