Evidence of Quantum Vacuum Birefringence from a Magnetar Astronomers using NASA’s IXPE X-ray polarimeter, supported by radio data from CSIRO’s Parkes telescope, report strong polarization signatures from the magnetar 1E 1547.0-5408 that match predictions of vacuum birefringence. The effect, first outlined by Heisenberg nearly 90 years ago, arises when an extreme magnetic field aligns virtual … Read more
