Bethe Colloquium

From axion dark matter to dark astronomy

by Joerg Jaeckel (Uni Heidelberg)


In this talk we start with the classical example of an oscillating cosmological field axion and axion-like particle dark matter. We will see that it is a suitable dark matter candidate, albeit one with interesting wave-like features that express themselves as coherent oscillations. We discuss existing and future probes of this type of dark matter. We also explore options for post-discovery physics, establishing the nature of dark matter and exploring a path to dark astronomy.
