A new measurement reported in Nature provides evidence for a new cooling property of dark matter posited by a collection of professors, postdoctoral fellows, and students from our department. The initial paper exploring the possibility of heat exchange between hydrogen and dark matter was authored in 2013 by Marc Kamionkowski, and two of his collaborators. Two subsequent papers elaborated further this heat exchange and proposed to seek evidence for it in precisely the type of measurements reported in Nature. One of these papers was authored by Joseph Silk, a JHU research professor, and his collaborators; the other paper was written by JHU postdocs Yacine Ali-Haïmoud and Ely Kovetz and a graduate student, Julián Munoz.
