  Black hole superradiance provides a window into the dynamics of light scalar
fields and their interactions close to a rotating black hole. Due to the
rotation of the black hole, the amplitude of the scalar field becomes
magnified, leading to a "black hole bomb" effect. Recent work has demonstrated
that rotating black holes in dynamical Chern-Simons gravity possess unique
structures, the "Chern-Simons caps," which may influence the behavior of matter
near the black hole. Motivated by the presence of these caps, we study
superradiance in dynamical Chern-Simons gravity in the context of a slowly
rotating black hole. We find that additional modes are excited and contribute
to the superradiance beyond what is expected for a Kerr black hole. Studying
the superradiant spectrum of perturbations, we find that the Chern-Simons
contributions give rise to small corrections to the angular dependence of the
resulting scalar cloud. Finally, we comment on potential observable
consequences and future avenues for investigation.
