Microlensing is the only tool to discover and study a population of hidden dark compact objects, including neutron stars, black holes and even the primordial black holes which could form part of the dark matter. We will show how LSST will contribute to this topic, with long-term whole sky observations and depth. We will discuss the lessons learned from Gaia and OGLE surveys which can be...
I shall describe some promising features of our Local Universe that can help reveal some feature of a particle DM candidate. Simulations of galaxy and DM structure formation of warm, cold and self-interacting DM candidates indicate that features of the Galactic and M31 halo like: tidal streams gaps, satellite galaxies orbit parameter distribution and their internal properties can differ...
