Vacuum birefringence and the polarized X-ray emission from a radio magnetar.
Magnetars are isolated neutron stars with exceptionally strong surface fields exceeding 10 14 G (ref.
Magnetars are isolated neutron stars with exceptionally strong surface fields exceeding 10 14 G (ref. 1 ). Their bright X-ray emission probes physical regimes in which quantum electrodynamics (QED) influences radiation propagation 2-4 . Strong magnetic fields induce…
