Description
Ultralight bosons exhibit coherent wave behavior when their occupation number reaches a significant threshold. If these bosons interact with the Standard Model sector of particle physics, their oscillating background can generate a minute signal. In the vicinity of a rapidly rotating black hole, ultralight bosons falling within a specific mass range can accumulate via superradiance, resulting in a high expected density. I will talk about how the utilization of the Event Horizon Telescope and neutrino detectors can detect and resolve the boson cloud. Additionally, terrestrial experiments employing quantum sensors, such as superconducting cavity and magnetometers, can significantly enhance the search for ultralight boson dark matter. The talk covers both theoretical advancements and experimental findings in this area of research.
