Gravitational Radiation from Superradiant Instabilities of Rotating Black Holes

We use the Teukolsky formalism to calculate the gravitational radiation from a non-axi\-symmetric cloud formed due to superradiant amplification of a spin-0 bosonic field. We focus on the prospects of the future space-based gravitational wave detector, Laser Interferometer Space Antenna (LISA), and the current version of ground-based detector, Advanced Laser Interferometer Gravitational-Wave Observatory (AdLIGO), to detect or constrain scalars with mass in the range m_s\in [10^-19,10^-15] eV and m_s\in[10^-14,10^-11] eV, respectively. Using astrophysical models of black hole populations calibrated to observations we find that, in optimistic scenarios, AdLIGO could detect up to 10⁴ resolvable events in a four-year search if m_s\sim3\times10^-13~eV, and LISA could detect up to 10³ resolvable events in a four-year search if m_s\sim10^-17~eV.
