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 transmit with unit probability via a Callan-Rubakov-like channel.

Scaling monopoles generate PBHs via stochastic overdensities and GWs with correlated spectra, potentially with magnetically charged PBHs as a signature if the scaling ends via gauge boson mass.
A self-consistent Parker bound, anchored in the dynamo seed eigenmode and including turbulent pre-acceleration of monopoles, relaxes the standard extended Parker bound by roughly two orders of magnitude at low and intermediate monopole masses.
Monopole bags in axionic backgrounds gravitationally collapse into horizonless states or dyonic regular black holes that evade singularities while retaining axionic hair.
In an SU(3) non-Abelian gauge theory, magnetic monopole number density is suppressed for small bias parameter ε of domain walls, allowing few monopoles to survive.
