Searching for dark matter in the sky
Dark matter’s gravitational imprints are observed across cosmic scales, yet its fundamental nature remains elusive. This colloquium explores astroparticle probes as a powerful means to investigate dark matter candidates across a vast range of masses and interaction types. I will discuss how diverse astrophysical observables—such as photons, cosmic rays, and other high-energy particles—can be harnessed to search for signatures of dark matter and new physics, from ultralight particles like axions to heavy relics such as primordial black holes. The talk will highlight recent advances in detecting these unique signatures, as well as the challenges in interpreting signals across vastly different mass scales.
