Descripción
As part of a systematic survey for the search of high velocity gas in giant extragalactic H II regions, the authors have observed the five largest and brightest H II regions in M101. They have found two types of peculiar emission profiles: (1) a broadening of the Hα emission line at low intensity, in excess of the values expected for the typical gaussian profile and (2) a very broad component (FWZI > 3000 km s-1) for Hα + the [N II] doublet, located at NGC 5471.
