Constraining Lorentz Violation Using Spectropolarimetry of Cosmological Sources

Abstract

Spectropolarimetry of distant sources of electromagnetic radiation at wavelengths ranging from infrared to ultraviolet are used to constrain Lorentz violation. A bound of 3x10^{-32} is placed on coefficients for Lorentz violation.
