• Using XMM-Newton data, we study the nuclear outflow of the nearby starburst galaxy NGC 253 in X-rays with respect to its morphology and to spectral variations along the outflow. Depending on the distance to the centre of the galaxy along its semi-minor axis, the RGS spectra show many individual emission lines with varying intensities. We present temperatures and the ionisation mechanism along the outflow in both directions away from the nucleus. Using images created from the RGS data, we find that the O VIII line emission clearly traces the morphology of the outflow. We see a clumpy distribution of emission, showing the hot mass-loaded wind for the first time. Emission at higher energies is more confined to the nucleus and the disc. Limb brightening of the outflow, as found in observations with Chandra and XMM-Newton, is confirmed, but it is limited to the energy range between 550eV and 750eV.
