Dark matter particles may scatter against each other only when they hit the right energy, say researchers in Japan, Germany, and Austria in a new study.  A team led by the Kavli Institute for the Physics and Mathematics of the Universe constructed a map of dark matter throughout the history of the universe by analysing images of more than ten million galaxies.  Key components for the sky-mapping Dark Energy Spectroscopic Instrument (DESI), weighing about 12 tons, were hoisted atop the Mayall Telescope at Kitt Peak National Observatory (KPNO) near Tucson, Arizona, and bolted into place Wednesday, marking a major project milestone.
