Abstract: Fast and energetic winds are invoked by galaxy formation models as essential processes in the evolution of galaxies. These outflows can be powered either by star-formation and/or AGN activity, but the relative dominance of the two mechanisms is still under debate. We use spectroscopic stacking analysis to study the properties of the low-ionization phase of the outflow in a sample of 1330 star-forming galaxies (SFGs) and 79 X-ray detected (42<br />MNRAS in press, 10 figures, 3 tables. Major update with respect to previous version: X-ray Chandra catalogues were upgraded to the latest available versions (Chandra 7Ms and COSMOS-Legacy). The mass-matched sample of SFGs was also re-defined. Major results are unchanged
