Axial tidal Love numbers for black holes in anisotropic fluid environments are derived analytically and numerically, with non-compact support density profiles producing logarithmic terms that obstruct standard tidal matching due to the lack of a strictly vacuum exterior.
Scalar clouds around black holes in mass-varying dark matter halos exist only for quantized scalar-dark matter couplings set by halo parameters such as compactness.
Analytic perturbative black hole solutions in dark photon models with minimal and higher-order magnetic dipole corrections to the Schwarzschild geometry.
A non-minimally coupled vector field reproduces Einstein cluster dynamics that account for flat galactic rotation curves.
Computes scalar and tensor fluxes for eccentric EMRIs with massive scalars, quantifies dephasing, and shows via Fisher matrix that LISA can constrain scalar charge and mass.
Regular black holes in Einasto dark matter halos show the strongest deviations from Schwarzschild in photon sphere and shadow properties near a critical halo parameter, remaining consistent with Sgr A* but mildly disfavoring M87* at high values.
A multi-parameter formalism is developed to describe asymmetric binaries in general matter distributions by perturbing around Schwarzschild and reducing metric and fluid perturbations to wave equations similar to the vacuum case.
Black hole spacetimes in dark matter spikes are solved analytically from TOV equations; ringdown quasinormal frequencies differ from Schwarzschild by up to order 10^{-4}.
Braneworld quadratic and nonlocal corrections weaken gravity in anisotropic Einstein-cluster environments around black holes, blocking horizon formation and shifting Einstein-ring and shadow radii in ways that may constrain brane tension for sub-stellar-mass objects.
