Abstract

High-angular-resolution observations of (C-12)O, (C-13)O, (C-18)O J = 1-0 and H53-alpha hydrogen recombination line emission from the energetic DR 21 outflow are presented and examined. The observations suggest that this outflow is probably the most massive (greater than 3000 solar masses) and energetic (greater than 2 x 10 to the 48th ergs) young-stellar outflow yet discovered in the Galaxy.
