Abstract

So far, dark matter has only been discovered gravitationally, while its particle identity remains unknown. It is possible that dark matter is so weakly coupled to the visible sector that a direct nongravitational interaction lies well beyond our experimental reach. It is then interesting to ask to what extent indirect probes of dark matter can point to a specific particle physics description. In this note, we discuss two such examples: The first is via 21 cm cosmology and the second is via the study of AGN and black hole growth rate.
