Colloquium with Professor Nicolao Fornengo, Department of Theoretical Physics, University of Torino, Italy

The identification of the origin of dark matter is an outstanding problem, connecting cosmology with particle physics. After an introduction to the dark matter problem, the talk will explore the landscape of methods and techniques that are currently pursued to try to identify in the fluxes of cosmic messengers those rare dark matter signals which are expected from the different structures that populate the universe (galaxies, galaxy clusters, cosmic voids and filaments) if dark matter is of particle origin.
