Resolved H ii Regions in NGC 253: Ionized Gas Structure and Suggestions of a Universal Density–Surface Brightness Relation

We use the full-disk Very Large Telescope/MUSE mosaic of NGC 253 to identify 2492 H ii regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the largest samples of highly resolved spectrally mapped extragalactic H ii regions. Regions of all luminosi...
