A map of the outer gas disk of the Galaxy with direct distances from young stars
Peter Craig, Sukanya Chakrabarti, Alexander R. Pettitt +2
For more than fifty years, astronomers have mapped the neutral hydrogen gas in the Galaxy assuming kinematically derived distances. We employ the distances of nearby young stars, w…
