Spectral–Geometric Regulation and Large-Scale Magnetic Context in Pulsar and Magnetar Radio Emission:

Recent radio observations increasingly suggest that pulsar and magnetar emission cannot be fully understood without reference to their broader magnetic environment. In particular, the Galactic magnetic field imprints frequency-dependent coherence, intermittency, and anisotropy on detected signals, complicating interpretation at both source and population levels. This paper examines how refined spectral–geometric additive–multiplicative (AM) regulation interacts with large-scale magnetic context in radio observations of pulsars and magnetars. Using curated samples of pulsar detections, magnetar radio events, and established Galactic magnetic field models, the author shows that AM-regulation enhances the visibility of magnetically coherent emission while preserving intrinsic source properties. The analysis demonstrates that regulation clarifies the coupling between local neutron star magnetospheres and Galactic-scale magnetic structure without introducing artificial spatial correlations. These results position spectral–geometric regulation as a conservative bridge between radio transient phenomenology and Galactic magnetism.
