Universailty of Low Energy Absorption Cross-sections for Black Holes
read the original abstract
In this paper we compute the low energy absorption cross-section for minimally coupled massles scalars and spin-$1/2$ particles, into a general spherically symmetric black hole in arbitrary dimensions. The scalars have a cross section equal to the area of the black hole, while the spin-$1/2$ particles give the area measured in a flat spatial metric conformally related to the true metric.

How traversable is a traversable wormhole?
Low-frequency scattering calculations show scalar probes through the MMP wormhole are mostly reflected or trapped at early times with late leakage to half the black-hole cross-section, while charged massless fermions ...

Polarization-dependent observational signatures of Weyl-coupled photons around a black hole
Weyl-coupled photons on Schwarzschild produce a polarization-split double shadow (62% edge separation at α/M²=0.75) and a parity-protected backward birefringence signal that vanishes at α=0.

Hawking Emission from Black Holes Evaporating toward Wormholes and the Accuracy of the WKB Approximation
Direct numerical greybodies for Simpson–Visser and CFM black holes near wormhole endpoints cut residual Hawking luminosity far below WKB estimates, raising a sample lifetime coefficient by ~85.

Accretion of multipolar massive complex scalar field packets by a Schwarzschild black hole
Mode-by-mode numerical accretion maps show that Gaussian massive scalar packets around a Schwarzschild black hole accrete with efficiency set by k0 and ℓ, acquiring a low-k0 partial-accretion floor when Rs/λC > 1.

Hawking Emission from Black Holes Evaporating toward Wormholes and the Accuracy of the WKB Approximation
Near the wormhole endpoint, the WKB approximation misestimates Hawking luminosities by orders of magnitude; direct numerical greybody factors lengthen an illustrative lifetime estimate by a factor of about 85.

For the ln(R)F² black hole, a single coupling B is claimed to shrink the shadow and ISCO, alter Dirac quasinormal ringing, suppress Hawking luminosity, and set the sign of an effective pressure on the topological defect line.
