Particle Astrophysics & Cosmology (PAC)

Meet the world’s deepest underground physics facilities.

Computer simulations and lab experiments help researchers understand the violent universe and could potentially lead to new technologies that benefit humankind.

A new experiment at the South Pole picks up where BICEP2 left off.

Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth’s surface, underground and in space.

Dark matter hunters of the LUX collaboration have ruled out a larger-than-ever range of properties that hypothetical dark matter particles might have had.

The Large Synoptic Survey Telescope’s ‘Eye’ Will be Built at SLAC.

The fellowship will support their research on new capabilities for the lab's X-ray free-electron lasers and new telescope technology to look for signs of cosmic inflation.

Researchers at SLAC are setting up a test stand and liquid xenon purification system for the future LZ experiment, which is scheduled to begin its search for dark matter particles in 2019.

Dark Energy Survey scientists have released a detailed map of dark matter – crucial information for a better understanding of galaxy formation and dark energy.

Reports by groups including Dark Energy Survey and Large Area Telescope scientists may provide new clues about the properties of mysterious dark matter.

Two recent meetings at SLAC brought together experts working on computer hardware and software for LSST – a future telescope that will provide unprecedented views of the sky and may solve some of the biggest mysteries of the universe.

When SuperCDMS SNOLAB turns on in 2018 at the underground science laboratory in Canada, it will be able to see dark matter particles 10 times lighter than previous searches.
