The structure of giant extragalactic HII regions
The existence of a close correlation between the linear diameters of giant HII regions in late type spiral and irregular galaxies and the width of their global H[subscript alpha] emission is demonstrated by means of line profiles obtained using interferometric techniques. The relation (diameter-line...
