With contributions from Brown faculty and students, the LUX-ZEPLIN experiment analyzed the largest dataset ever collected by ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of ...

The world’s most sensitive dark matter detector still hasn’t found evidence of weakly interacting massive particles, or WIMPs, but the search continues. LZ’s central detector, the time projection ...

Far beneath the Black Hills of South Dakota, a tank of liquid xenon is quietly recording some of the faintest signals in the ...

For nearly a century, dark matter has been the invisible scaffolding of the universe, inferred from its gravitational pull ...

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s ...

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These ...

Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive ...

Andrea Gallo Rosso is a member of the ALPHA collaboration. He receives funding from the Swedish Research Council. Several experiments have aimed to unveil what it’s made of, but despite decades of ...

The LZ's central detector in a surface lab clean room before delivery and installation underground. Located deep underground, the LZ (Lux-Zeplin) detector takes elaborate precautions to screen out ...

New results from the world’s most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe’s invisible mass. Figuring out ...
