Query: Lorentz-violation-induced arrival delays of cosmological particles   We point out that previous studies of possible Lorentz-violating effects in
astronomical time-of-flight data did not take into account the entire
implications of the universe's cosmological expansion. We present the
derivation of the accurate formulation of the problem and show that the
resulting correction of the limits on Lorentz violation is significant.
