Description
I discuss several connections between black hole phenomenology and dark matter searches. In the first part of the talk, I consider the idea that black holes of primordial origin constitute a portion of the dark matter that permeates the Universe, and explore the consequences of this idea in a cosmological context, discussing the upper limit on their abundance obtained by analyzing the angular power spectrum of the Cosmic Microwave Background. In the second part, I show how dark matter over-densities around black holes can leave a fingerprint on gravitational wave signals, and demonstrate that the upcoming LISA experiment has the potential to discover such signatures and hence indirectly detect dark matter.
