SLAC cosmologists are using multiple images of the same quasars, produced by massive galaxies’ gravitational pull, to calibrate cosmic distances. Their work may help resolve long-standing debates about how quickly the universe is expanding.

Crews building the LUX-ZEPLIN dark matter experiment have overcome COVID-19 obstacles to reach a major milestone en route to startup.

Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy.

The LUX-ZEPLIN collaboration has published results showing radioactive background levels for experiment’s components, creating a library for future rare event searches.

Sensors of world’s largest digital camera snap first 3,200-megapixel images at SLAC

The camera will explore cosmic mysteries as part of the Rubin Observatory’s Legacy Survey of Space and Time.

The technology could save the lives of COVID-19 patients when more advanced ventilators are too expensive or not available.

Observations of dwarf galaxies around the Milky Way have yielded simultaneous constraints on three popular theories of dark matter.
