Astrophysical implications of hypothetical stable TeV-scale black holesJun 2008 Untraced · nothing upstream recorded

White dwarfs and neutron stars are known to have significant magnetic fields, which can have important effects on the charged cosmic-ray primaries.

Astrophysical implications of hypothetical stable TeV-scale black holesextraction 0.75

Section 6.1 ("Magnetic screening") of the LHC black-hole safety analysis, which develops the argument that strong dipole fields deflect and radiatively degrade charged ultra-high-energy cosmic rays before surface impact; this screening is why the paper's empirical bounds rest chiefly on weakly magnetized white dwarfs rather than typical neutron stars.
