The formation and growth of black holes can strongly influence the distribution of dark matter around them. I discuss here the different types of dark matter overdensities around black holes, including dark matter cusps, spikes, mounds, crests, and gravitational atoms. I then review recent results on the evolution of a black holes binary in presence of dark matter, focusing on the energy transfer between binary and dark matter induced by dynamical friction. Finally, I present the prospects for studying dark matter with gravitational wave observations, and argue that future interferometers might be able to detect and characterise dark matter overdensities around black holes.

  1. The Ringdown and the Tide: Fingerprints of Dark Matter Halo Profiles

    gr-qc 2026-08 conditional novelty 6.0 of 10

    For black holes in generalized (alpha,beta,gamma) dark matter halos, the axial ringdown shift is set by a single redshift integral, while the tidal Love number depends on an outer radial moment, making the two observa...

  2. Dark matter environments and safeguards for spacetime inference from horizon scale interferometry

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Using public 2017 M87* closure data, a frozen Kerr source fails an absolute adequacy test and the differential tidal-charge response fails numerical convergence, so no posterior or bound is reported.

  3. BinaryGFH-v2: Improved method to search for gravitational waves from sub-solar-mass, ultra-compact binaries using the Generalized Frequency-Hough Transform

    gr-qc 2025-12 conditional novelty 6.0 of 10

    BinaryGFH-v2 is a modified GFH method that can search for inspiraling binaries with chirp masses 0.01–0.1 solar masses, validated in Gaussian noise and projected to constrain PBH dark matter.

  4. Tidal Love numbers and quasi-normal modes of the Schwarzschild-Hernquist black hole

    gr-qc 2024-12 conditional novelty 6.0 of 10

    For a Schwarzschild black hole in a relativistic Hernquist dark matter halo, quasinormal-mode frequency shifts scale as (MDM/rs)^(3/2) rather than linearly, while tidal Love numbers are small and sensitive to the choi...

  5. Static Dark Fluid Thin Shells in Schwarzschild-de Sitter Spacetimes: Stability and Black Hole Shadows

    gr-qc 2026-02 conditional novelty 5.0 of 10

    Stable static dark-fluid shells separating two Schwarzschild–de Sitter spacetimes exist only for m_+/m_->1 and arise at three scales, imprinting observable black-hole shadow deviations.
