Annihilation radiation from neutralino dark matter at the Galactic center (GC) would be greatly enhanced if the dark matter were strongly clustered around the supermassive black hole (SBH). The existence of a dark-matter "spike" is made plausible by the observed, steeply-rising stellar density near the GC SBH. Here the time-dependent equations describing gravitational interaction of the dark matter particles with the stars are solved. Scattering of dark matter particles by stars would substantially lower the dark matter density near the GC SBH over 10^10 yr, due both to kinetic heating, and to capture of dark matter particles by the SBH. This result suggests that enhancements in the dark matter density around a SBH would be modest whether or not the host galaxy had experienced the scouring effects of a binary SBH.

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.

Scalar fields around black hole binaries in LIGO-Virgo-KAGRA
Semi-analytic waveform model for scalar environments around black hole binaries is validated against numerical relativity and applied to LIGO-Virgo-KAGRA data to obtain upper limits on scalar densities with tentative ...

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...

Darkness Visible: N-Body Simulations of Dark Matter Spikes in Hernquist Haloes
N-body simulations of adiabatic black hole growth in Hernquist haloes yield an empirical spike profile with outer halo depletion and a mass-ratio-dependent spike radius that deviates from analytical predictions.

Probing the sensitivity of CTAO-N LSTs observations at large zenith angles to the multi-TeV gamma-ray emission from the inner 10 parsecs of the Galactic Center
A simulation predicts that 500 hours of CTAO-North four-LST observations at large zenith angles can discriminate between dark-matter, millisecond-pulsar, and proton-induced models of the Galactic Center TeV source HES...

Road through Dark$\nu$ess: Probing dark matter-neutrino interactions using KM3-230213A
Using the 220 PeV event KM3-230213A, the authors set the highest-energy constraints to date on dark matter-neutrino scattering, and for energy-dependent cross sections they report some of the strongest existing limits.
