Descripción
One possible and natural derivation from the collisionless cold dark matter (CDM) standard cosmological framework is the assumption of the existence of interactions between dark matter (DM) and photons or neutrinos. Such interacting DM models would imply a suppression of small-scale structures due to a large collisional damping effect and can help alleviate alleged tensions between standard CDM predictions and observations at small mass scales. In this talk, I will present the properties of DM subhalos formed in a high-resolution cosmological N-body simulation specifically run within these alternative models. I will also compare our results with the one obtained in the standard cosmological scenario. These results have a direct application on studies aimed at the indirect detection of DM where subhalos are expected to boost the DM signal when the CDM model is assumed. I will briefly investigate its role in the interacting DM model presented in this talk.
