Abstract
We derive new bounds on Lorentz violations in the electron sector from existing data on high-energy astrophysical sources. Synchrotron and inverse Compton data give precisely complementary constraints. The best bound on a specific combination of electron Lorentz-violating coefficients is at the level, and independent bounds are available for all the Lorentz-violating coefficients at the level or better. This represents an improvement in some bounds by 14 orders of magnitude.
