Description

Areas of massive star formation are heavily affected by stellar winds and supernovae, therefore we expect enhanced turbulent flows in such regions. I present kinematic properties in dwarf galaxy DDO 43 (d = 7.8 Mpc), revisiting the high-resolution HI 21-cm VLA spectra of the LITTLE THINGS survey. The line profiles are carefully analysed in the CLASS radioastronomical data reduction software, and the resulting distribution maps of spectral line properties are investigated together with available GALEX and WISE data, to provide additional insights to the characteristics of local and global neutral gas flows in massive star forming regions.
