Theory SeminarStrong Gravity Frontier of Particle Physics
Yifan Chen (Nils Bohr Institute)
Outside of black holes, particle density can significantly increase, acting as efficient transducers. This is evident in the superradiant generation of ultralight bosons, which can attain Planck-scale field values. Within this dense boson environment, we witness the occurrence of non-perturbative particle production—a phenomenon previously associated primarily with the early-universe cosmology. Additionally, particle dark matter can accumulate outside black holes forming spike structures. This talk will explore their impact on various observational channels associated with black holes, such as the Event Horizon Telescope and high-energy neutrino observations.
