The events of the last few weeks have been deeply upsetting, and many members of our community are struggling as a result. This is an especially difficult time for our Black colleagues and friends, and it is a reminder that those of us who are in positions of privilege have a responsibility to show our support. We affirm our group’s commitment to inclusion and diversity, and we encourage our members to support anti-racism and advocate for the Black members of our community. We are committed to stand with our colleagues to build more just and equitable communities, both within and outside of science.


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 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.


In an article submitted to Physical Review D, CPC members Noah Kurinsky and Gordan Krnjaic collaborate with Dan Baxter (KICP) and Yoni Kahn (UIUC) to present a novel interpretation of excess events observed at various low-threshold dark matter searches. They found that the anomalous results across various detectors operating in dramatically different experimental conditions could… More »

The SPT-3G experiment began its 2020 winter observing season on March 23, 2020.  The SPT-3G camera on the South Pole Telescope (SPT) is undertaking a 1500 square degree survey of the cosmic microwave background, the light left over from the Big Bang.  SPT is located at the geographic South Pole, and takes some of its… More »

The Dark Energy Spectroscopic Instrument seeks to further our cosmic understanding by creating the largest 3-D map of galaxies to date. Below is a press release issued by Lawrence Berkeley National Laboratory announcing first light for this extraordinary instrument. The U.S. Department of Energy’s Fermi National Accelerator Laboratory is a key player in the construction of… More »
