✦ Synopsis

We study analytically a system sustaining stable moving localized structures, namely, the one-dimensional quintic complex Ginzburg-Landau (G-L) equation with non-linear gradients. We obtain approximate solutions for the stable moving pulse and its velocity. The results are in excellent agreement with direct numerical simulations.
