Fermilab’s cosmic research program explores the fundamental nature of matter, energy, space, and time, as revealed in the unique natural laboratory of the cosmos.

Surveys of galaxies and cosmic background radiation use precise measurements of cosmic structure to learn about fundamental physics of cosmic acceleration, new forms of gravitating matter, and properties of cosmic neutrinos. A coordinated campaign of experiments seek to directly detect and study the properties of dark matter particles in the laboratory. Development of new technology, both ultra-sensitive detectors and advanced computational algorithms, will enable the next generation of discovery.

The Fermilab Cosmic Physics Center (CPC) hosts Fermilab’s cosmic research program and fosters interactions between the lab and the larger the cosmic physics community. We invite you to join the adventure, a high-energy, cosmic journey: learn about who we are, the science we’re focused on, and how you can be a part of it.


The CPC is hosted the Dark Wave Lab workshop on April 15-16, 2024. Over 80 in-person and remote participants joined to discuss plans for creating a shared facility for axion search experiments at Fermilab.  

UChicago KICP and Fermilab CPC co-hosted a Stage-5 Spectroscopic Experiment (Spec-S5) instrumentation workshop from Feb 27 – Mar 1, 2024. As part of this workshop, participants toured Fermilab and saw the new CCD packaging and testing facilities at the Integrated Engineering Research Center (IERC).

The Fermilab Cosmic Physics Center is proud to welcome five new Fermilab Cosmic Physics Center Fellows. Profs. Kyle Dawson (University of Utah), Klaus Honscheid (Ohio State University), Paul Martini (Ohio State University), Marcelle Soares-Santos (University of Michigan)  – Coordinated R&D for a Stage-5 Spectroscopic Facility Dr. Fernando Chierchie (CONICET, Universidad Nacional del Sur) – Readout… More »
