Particle Astrophysics & Cosmology (PAC)

The scientists develop methods to study neutrinos from star explosions and search for unknown particles and forces with possible ties to dark matter.

The first website to be hosted in the US has grown to be an invaluable hub for open science.

In its final run, the LUX experiment increased its sensitivity four-fold, but dark matter remains elusive.

The goal: Develop high-tech coatings that make the detector’s mirrors less “noisy”.

Before Hitomi died, it sent back X-ray data that explain how turbulent motions may prevent cooling of hot gas.

A small-scale version of the future detector allows researchers and engineers to test, develop and troubleshoot various aspects of its technology.

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.
