| Abstract: | We present optical high-spectral-resolution long-slit observationsof massive star formation regions in the nearby galaxies M101, NGC2403, and M33 obtained with the WHT. We have constructed velocity,line dispersion and intensity maps using between 6 and 12 parallelslits in each case. We will present the data for seven regions:NGC 5455, NGC 5461, NGC 5471 in M101; three regions in NGC 2403;and NGC 595 in M33. We will also present a detailed study of thedifferent profiles found across the regions, paying specialattention to the presence of supersonic profiles and multiplecomponents. |
