| Abstract | By comparing radial velocities of radio-bright compact H II regions with their H I absorption spectra, we have discovered expanding shells of neutral hydrogen around them. These shells are revealed by absorption of the radio continuum emission from the H II regions at velocities indicating greater distances than the observed radial velocity. We believe that these shells are shock zones at the outer edges of the expanding ionized regions. |
