Breaking Parameter Degeneracies in a Magnetically Charged Black Hole Embedded in a Hernquist Dark-Matter Halo: A Multi-Observable Analysis

Ali Ovgun, Joel Saavedra, Reggie C. Pantig

A black hole with magnetic charge inside a Hernquist dark matter halo shows opposing shifts in its ringing frequencies, shadow size, light deflection, and neutrino annihilation rate from the two effects.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

These results show that ringdown, imaging, lensing, and high-energy deposition probe the same underlying competition between near-horizon magnetic structure and extended dark-matter environment, but with different parameter weights.

C2weakest assumption

The assumed static spherically symmetric metric is an exact solution of the Einstein equations sourced by nonlinear electrodynamics and the Hernquist halo, and the high-order WKB plus Pade resummation accurately reproduces the true quasinormal spectrum without significant truncation error.

C3one line summary

Computations for a new black hole metric with magnetic charge and Hernquist halo show that charge raises QNM frequencies while the halo lowers them, with similar opposing effects on shadow size and neutrino annihilation efficiency.
