Figure shows the spectrum of two galaxies at redshifts 2.587 and 3.479 in the UDS and CDFS field (top and bottom panels, respectively) with the combined fit of low-ionisation absorption lines (red), and for which we detect significant inflow signatures, with positive ISM velocity shifts as indicated in each panel (i.e. the centroids of ISM absorption lines are redshifted compared to the C III] centroid used for the systemic redshift).
