(dedicated to the science of Georg G. Raffelt)
In this edition of Current Topics in Astroparticle Physics, we will set the stage for discussing both the longstanding and the new puzzles in astroparticle theory and experiment. Among the plethora of topics available, we shall mildly favour those to which our honoured Georg G. Raffelt devoted part of his extraordinary career. We will discuss (quite) weakly interacting particles (neutrinos, the hypothetical axion, or weakly interacting dark matter candidates), their role in astrophysics and cosmology, and conversely, what we can learn about their properties from astrophysical and cosmological arguments and observations.
