Internal turbulence, viriality, and density bounding of the most luminous H II regions in the spiral galaxy M 100
We present TAURUS Fabry-Perot velocity data in Hα emission of the disc of the grand design spiral M 100 (NGC 4321). We have studied the emission spectra of the 200 H ii regions most luminous in Hα, calibrated in luminosity using photometric Hα imaging from the literature. The emission spectra of individual H ii regions were fitted using one or more
