To capture as much information as possible about clouds of atoms at the heart of the MAGIS-100 experiment, SLAC scientists devised a dome of mirrors that gathers more light from more angles.

They’ll work on experiments that search for dark matter particles and exotic neutrino decays that could help explain why there’s more matter than antimatter in the universe.

Edelen draws on machine learning to fine tune particle accelerators, while Kurinsky develops dark matter detectors informed by quantum information science.

The Rubin Observatory's LSST Camera will take enormously detailed images of the night sky from atop a mountain in Chile. Down below the mountain, high-speed computers will send the data out into the world. What happens in between?

DESI has already mapped out more galaxies than all previous 3D surveys combined, and it's just getting started.

Managing the unprecedented amount of data that will soon stream from Rubin Observatory means more than buying tons of hard drives. SLAC scientist Richard Dubois explains what will go into Rubin’s U.S. data facility.

A new analysis of the South Pole-based telescope’s cosmic microwave background observations has all but ruled out several popular models of inflation.

Fulfilling a prediction of Einstein’s theory of General Relativity, researchers report the first-ever recordings of X-ray emissions from the far side of a black hole.

From the invisible world of elementary particles to the mysteries of the cosmos, recipients of this prestigious award for early career scientists explore nature at every level.

An international collaboration aims to create a 3D map of the universe, unraveling the mysterious nature of dark energy.

Rebecca Leane and colleagues showed dark matter could heat planets in our galaxy to incredible temperatures. Here, she explains how that works and how it could pave the way for sensitive new searches for the mysterious substance.

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.
