O frabjous day! Callooh! Callay!
Our paper on theoretically-derived constraints on the supernova thermalization efficiency and central mass loading of M82's starburst-driven galactic wind is no longer "in press," but has been published. No longer will you have to make do with the arXiv preprint version.
