Description
Gravitational particle production from black holes offers a novel avenue for exploring particle physics, particularly in the case of dark sector particles whose non-gravitational interactions remain beyond the reach of conventional laboratory searches. In this talk, I will discuss two production mechanisms: Hawking radiation and Superradiance. Via Hawking radiation, black holes can generate particles from both the Standard Model sector and the dark sector. Additionally, the presence of bosonic particles within the dark sector can modify the spin dynamics of black holes through the Superradiance process, which can further be discerned with the Hawking radiation spectrum. In the end, I will show how upcoming gamma-ray and X-ray observations could shed light on both primordial black holes and the dark sector.
