Off-Equatorial Orbits around Magnetically Charged Black Holes
Xilai Li, Loris Del Grosso, David E. Kaplan
We present a complete characterization of stable, off-equatorial circular orbits around magnetically charged black holes (MBHs). For a static, spherically symmetric MBH, we derive…

We show that both abelian and non-abelian gauge theories admit configurations in which the fields behave as if in the presence of static charge densities, or ``shadow charges". The…
