Definitions

A distance of ten parsecs

Examples

“In most models, the direction of the magnetic field is random, but if the axial field is generated by a Cosmic Battery generated by current in the direction of rotation in the accretion disk, there is a correlation between the directions of the spin⟳ of the AGN accretion disk and of the axial field, which leads to a specific direction for the axial electric current, azimuthal magnetic field, and the resulting observed transverse Faraday-rotation (FR) gradient across the jet, due to the systematic change⟳ in the line-of-sight magnetic field. We consider⟳ new observational evidence for the presence of a nested helical magnetic-field structure⟳ such as would be brought about by the operation of the Cosmic Battery, and make⟳ predictions about the expected behavior of transverse FR gradients observed on decaparsec and kiloparsec scales.”
