Supercomputer comes up with profile of dark matter

3 November 2016 Astronomy Now

In the search for the mysterious dark matter, physicists have used elaborate computer calculations to come up with an outline of the particles of this unknown form of matter. The scientists extended the successful Standard Model of particle physics which allowed them, among other things, to predict the mass of so-called axions, promising candidates for dark matter.

‘Stealth dark matter’ theory may explain universe’s missing mass

25 September 2015 Astronomy Now

A Lawrence Livermore National Laboratory team has combined theoretical and computational physics techniques using the Laboratory’s 2-petaflop Vulcan supercomputer to devise a new model of dark matter. They found that dark matter is “stealthy” today, but would have been easy to detect in the extremely high-temperature plasma conditions that pervaded the early universe.
