Resolution of the Distance Ambiguity for Galactic HII Regions

We resolve the kinematic distance ambiguity for 266 inner Galaxy H II regions out of a sample of 291 using existing H I and (CO)-C-13 sky surveys. Our sample contains all H II regions with measured radio recombination line emission over the extent of the (CO)-C-13 Boston University-Five College Radio Astronomy Observatory Galactic Ring Su...更多
