Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.

Scientists are designing a next-generation experiment to map the Big Bang’s relic afterglow.

Latin America has reached a pivotal moment in experimental particle physics and astrophysics research. Throughout the month of October, Symmetry will explore how.

Early-career physicist Jonathan LeyVa helps build one of the world’s most sensitive dark matter detectors.

An “out there” theory inspired the development of the Dark Matter Radio, a device that could explain the mysterious matter that makes up 85 percent of the mass of our universe.

The complete data from the EXO-200 experiment provide new information on neutrinoless double beta decay and set the stage for future experiments that will search for the hypothetical process.

At SLAC’s FACET facility, researchers have produced an intense electron beam by 'sneaking’ electrons into plasma, demonstrating a method that could be used in future compact discovery machines that explore the subatomic world.

If a particle has no mass, how can it exist?

A SLAC/Stanford study of the population of satellite galaxies orbiting the Milky Way provides new clues about the particle nature of dark matter.

Particle accelerators are some of the most complicated machines in science.

Four large meshes made from 2 miles of metal wire will extract potential signals of dark matter particles.

The approach could advance our understanding of fundamental forces under extreme conditions with applications from astrophysics to fusion research.
