X-ray Polarization from Magnetar 1E 1547.0−5408 Supports Long-Predicted Vacuum Birefringence

Nature study finds unusually strong, phase-resolved X-ray polarization from magnetar 1E 1547.0−5408, evidence consistent with QED vacuum birefringence.

IXPE observations strengthen evidence for vacuum birefringence around magnetar 1E 1547.0−5408

IXPE X-ray polarimetry, NICER and Parkes radio data show strong, phase-dependent polarization from magnetar 1E 1547.0−5408, supporting vacuum birefringence.
