Gravitational waves can provide crucial insights about the environments in which black holes live. In this work, we use numerical relativity simulations to study the behaviour of self-interacting scalar (wave-like) dark matter clouds accreting onto isolated and binary black holes. We find that repulsive self-interactions smoothen the ``spike'' of an isolated black hole and saturate the density. Attractive self-interactions enhance the growth and result in more cuspy profiles, but can become unstable and undergo explosions akin to the superradiant bosenova that reduce the local cloud density. We quantify the impact of self-interactions on an equal-mass black hole merger by computing the dephasing of the gravitational-wave signal for a range of couplings. We find that repulsive self-interactions saturate the density of the cloud, thereby reducing the dephasing. For attractive self-interactions, the dephasing may be larger, but if these interactions dominate prior to the merger, the dark matter can undergo bosenova during the inspiral phase, disrupting the cloud and subsequently reducing the dephasing.

Ultralight Boson Ionization from Comparable-Mass Binary Black Holes
Ionization of boson molecules bound to a black hole binary can dominate gravitational-wave losses during early inspiral, imprinting a turnover in the nanohertz GW background and circularizing the orbit.

Kerr black holes with vector dark matter hair
Massive vector dark matter forms a r^{-3/2} density spike around a Kerr black hole and, for co-rotating low-frequency modes, extracts mass and angular momentum through superradiant scattering.

Matter environments around black holes: geodesics, light rings, and ultracompact configurations
Dark-matter halos modeled as Einstein clusters generically move the ISCO inward and the light ring outward, and ultracompact halos can add extra light rings, trapped modes, and secondary horizons.

Beyond general relativity: gravitational waves in non-minimally coupled theories
A generalized propagation parameterization for gravitational-wave strains is extended to O(H²) and O(H′), then mapped to Kalb-Ramond, axion-dilaton–Chern-Simons–Gauss-Bonnet, and U(1) dark-photon models.
