Description
Using recent polarimetric observations of the Crab Nebula in the hard X-ray band by INTEGRAL, we show that the absence of vacuum birefringence effects constrains O(E/M) Lorentz violation in QED to the level |ξ|<9x10-10 at 3σ CL, tightening by more than 3 orders of magnitude previous constraints. We show that planned X-ray polarimeters have the potential to probe |ξ|∼10-16 by detecting polarization in active galaxies at red-shift ∼1.
