New Technique Looks for Dark Matter Traces in Dark Places

Illustration - In this composite image, theorized particles of decaying dark matter should produce a spherical halo of X-ray emission – represented here as colorized matter concentrated around the center of the Milky Way (in black and white) – that could be detectable when looking in otherwise blank regions of the galaxy.

Berkeley Lab Cosmologists Are Top Contenders in Machine Learning Challenge

Image - The 2020 LHC Olympics, a machine learning challenge, challenged teams to develop codes that could find a hidden signal in particle-collision data. This image shows particle-collision data captured by the ATLAS detector at CERN's Large Hadron Collider. (Credit: CERN)
