Stringent constraints on the light boson model with supermassive black hole spin measurements
Lei Zu, Lei Feng, Qiang Yuan +1
Massive bosons, such as light scalars and vector bosons, can lead to instabilities of rotating black holes by the superradiance effect, which extracts energy and angular momentum f…
