We study a spherically symmetric fluctuation of scalar dark matter in the cosmos and show that it could be the dark matter in galaxies, provided that the scalar field has an exponential potential whose overall sign is negative and whose exponent is constrained observationally by the rotation velocities of galaxies. The local space-time of the fluctuation contains a three dimensional space-like hypersurface with surplus of angle.

Eccentricity-Modulated Phase Degeneracy and Distinguishability between Dark Matter and Accretion Disk Environmental Effects in EMRIs
DM dephasing in EMRIs is nearly eccentricity-independent while disk dephasing is strongly suppressed by e0, so residual SNR and distinguishability time favor slightly eccentric orbits for LISA separation of the two effects.

Extreme-Mass-Ratio Inspirals Embedded in Dark Matter Halo: Existence of Homoclinic Orbit and Horizon-Induced Chaos
A Schwarzschild black hole embedded in a Dehnen dark-matter halo admits homoclinic orbits, and raising halo density, scale radius, or particle energy drives near-horizon motion from regular to chaotic while respecting...

Probing Dark Matter and Phantom Field Effects on Neutrino Oscillations around Black Holes
For neutrinos deflected by a black hole embedded in phantom-field dark matter, the oscillation phase gains a logarithmic dark matter correction, while radially moving neutrinos see no net gravity effect.

Schwarzschild-like Black Holes Submerged in an Exponential Density Dark Matter Profile
An analytic Schwarzschild-like metric with an exponential dark matter halo is constructed and its shadows, quasi-normal modes, and greybody bounds are computed, though several derived expressions have sign errors.

Ringdown of a black hole sourced by a Burkert-density effective anisotropic source
The Burkert-halo black hole metric and its quasinormal-mode shifts are computed, but the model's source is not Burkert and the axial gravitational potential is incorrect.
