The Springtime Blues: Understanding Seasonal Allergies

When T.S. Eliot wrote the opening to The Waste Land, his primary intention was to capture the disillusionment of the post-World War I generation. For seasonal-allergy sufferers, however, a line such as “April is the cruellest month…” must take on a dual meaning. Indeed, sometimes the most annoying symptoms are also the most harrowing, so for those 40 million Americans who bear runny noses and watery eyes through the spring and into the summer, there might as well be a war going on in the cellula ...More »

Statistics of Turbulence Probed by H2O Masers in Star Forming Regions
Article imageABSTRACT 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
Article imageABSTRACT 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…
