      abstract     = {Discretizing Maxwell's equations in Galilean (comoving)
                      coordinates allows the derivation of a pseudospectral solver
                      that eliminates the numerical Cherenkov instability for
                      electromagnetic particle-in-cell simulations of relativistic
                      plasmas flowing at a uniform velocity. Here we generalize
                      this solver by incorporating spatial derivatives of
                      arbitrary order, thereby enabling efficient parallelization
                      by domain decomposition. This allows scaling of the
                      algorithm to many distributed compute units. We derive the
                      numerical dispersion relation of the algorithm and present a
                      comprehensive theoretical stability analysis. The method is
                      applied to simulations of plasma acceleration in a
                      Lorentz-boosted frame of reference.},
