Proper Motions and the Distance to a Water Vapor Maser in the Galaxy M33
Published online by Cambridge University Press: 12 April 2016
Abstract
The relative proper motions of water vapor maser features in the H ɪɪ region IC 133 have been used to determine a distance to the galaxy M33 that is independent of the usual calibrations associated with extragalactic distance estimates, e.g., extinction and metallicity.
