These particles may make up dark matter and may be produced thermally inside the cores of neutron stars, escape the stars due to their feeble interactions with matter, and …

Using the polarization data from ESA’s Planck satellite, a mission that have studied the Cosmic Microwave Background (CMB), the oldest light in the Universe, a duo of astrophysicists has uncovered intriguing signs of new physics beyond the Standard Model of elementary particles and fields. As the CMB light (left image) …
