We describe a quasi-equilibrium profile of dark matter particles in the inner parsec of the Galaxy, rho ~ r^-3/2. This "mini-cusp" profile is caused by scattering with the dense stellar cluster around the supermassive black hole in Sgr A* and is independent of the initial conditions. The implications for detection of gamma rays from WIMP dark matter annihilation in the Galactic center are a mild enhancement of the flux, and a characteristic central feature in the angular distribution which could be detectable by high-resolution Atmospheric Cherenkov Telescopes.

Scattering of wave dark matter by supermassive black holes
A first-principles scattering calculation explains the co-rotating wave dark matter profile around supermassive black hole binaries and predicts resonant power peaks that could imprint on the pulsar timing array spectrum.

Flavorful Interactions of AGN Neutrinos with Dark Matter Spike
IceCube-Gen2 flavor ratios can discriminate a U(1) neutrino–dark-matter model in AGN spikes from the standard (1/3:1/3:1/3) and muon-damped predictions, and, combined with mass-ordering and tau-decay data, constrain t...

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

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

High-Energy Neutrinos from Black Hole Evaporation in Neutron Stars
Repeated collapse of asymmetric dark matter inside neutron stars into evaporating microscopic black holes can produce a Galactic-Center-concentrated high-energy neutrino flux at the 10^-12 GeV cm^-2 s^-1 level, subdom...

Dark matter energy exchange in stars orbiting supermassive black holes
Orbit-averaged elastic DM scattering in S4714 reaches stellar luminosity at σ_χp ∼ 10^{-36} cm² (MeV–GeV) and σ_χe ∼ 5×10^{-38} cm² (sub-MeV) for a spiked profile.

Extracting Properties of Dark Dense Environments around Black Holes from Gravitational Waves
A novel quantity derived from GW signals encodes the density profile of dark dense environments around black holes, allowing characterization of the condensate type and DM properties via multi-wavelength observations.

Amplified capture rate of dark matter in compact binaries and constraints on bosonic dark matter from GW170817
Dark matter capture onto neutron stars is amplified by about 4-5 times in circular binaries, tightening cross-section limits from GW170817 and capping the accreted DM fraction near 1e-3.

Resonant DM scattering in the galactic center under the influence of EMRI
Repeated tidal resonances from an inspiralling EMRI secondary shift a dark matter particle's semi-major axis by less than one percent, leaving the DM spike nearly intact in the non-overlapping-orbit regime.

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

Sub-GeV dark matter scattering off protons in blazar jets can produce the IceCube neutrino from TXS 0506+056 while evading current dark matter constraints.

Phenomenology of Neutrino-Dark Matter Interaction in DSNB and AGN
Upper limits on the scalar-dark-matter neutrino coupling are derived from DSNB attenuation projected for DUNE/Hyper-K and from IceCube data on NGC 1068 and TXS 0506+056, assuming DM spikes around AGN black holes.

Relaxing Constraints on Dark Matter Annihilation Near the Supermassive Black Hole in M87
For a Burkert cored M87 halo, the smooth halo, not the black hole density spike, controls the annihilation signal, so M87 constraints on dark matter annihilation weaken by orders of magnitude.

Chaotic imprints of dark matter in extreme mass-ratio inspirals
A toy model shows that adding a hand-made angle-dependent force to dark-matter spacetimes produces visual chaos and irregular numerical-Kludge waveforms, but the force is not a realistic dark-matter perturbation.
