This lecture by Miguel Zilhão from the University of Aveiro explores the fascinating interactions between black holes and scalar fields, particularly in the context of dark matter candidates. Discover how self-gravitating structures of light fundamental fields might be common throughout the universe and potentially form galactic haloes. Learn about what happens when a black hole pierces through a larger relativistic boson star composed of complex minimally coupled massive scalar fields. The presentation examines how this interaction slows the black hole through accretion and dynamical friction, generating gravitational wave emissions. The speaker presents evidence for the formation of a "gravitational atom" as a result of this cosmic collision process, offering new insights into black hole dynamics and their relationship with scalar field structures.
