Astrophysics and cosmology

As the massive LSST camera project reaches its culmination, Hannah Pollek is one of the engineers in the clean room each day putting the pieces together.

His work aims to deepen our understanding of dark matter, dark energy and other secrets of the universe.

The Dark Energy Spectroscopic Instrument begins final testing, setting the stage for a 5-year survey that will analyze the light of 35 million galaxies.

Chemist Ben Ofori-Okai investigates what happens to matter under extreme conditions at microscopic scales to better understand its behavior at massive scales, such as what happens in the Earth’s core.

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

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

Maria Elena Monzani prepares an international team to search for clues to one of the biggest scientific mysteries.

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

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

SLAC completed its work on ComCam, a commissioning device to be installed in Chile later this year.

Building the Large Synoptic Survey Telescope also means solving extraordinary technological challenges.

In the decade since LCLS produced its first light, it has pushed boundaries in countless areas of discovery.
