Statistics of Turbulence Probed by H2O Masers in Star Forming Regions

ABSTRACT Using interferometric maps, the statistical properties of the velocity fields traced by H2O masers in five galactic regions of star formation were investigated. In a previous work, Strelnitski et al. (2002) concluded that H2O masing spots in such regions appear to probe highly intermittent supersonic turbulence and demonstrated that the two-point velocity correlation functions for the line-of-sight components of velocity traced by th…

Statistics of the Velocity Field and Spatial Distribution of Hot Spots in Methanol Masers

ABSTRACT We present the results of the first study of statistical properties of velocity field and spatial distribution of the observed “hot spots” in methanol maser sources with available interferometric maps. Three Class I sources and one Class II source were investigated. In the majority of the sources, both the velocity difference between the pairs of spots and the average number density of the neighbors to a spot are a…
