The Dark Energy Survey (DES) Collaboration announced the latest results combined weak lensing and galaxy clustering and incorporated four dark energy probes from a single experiment for the first time. This is the culmination of more than 20 years of work by the DES, which was proposed in 2005. Fermilab led the construction of the… More »

Videos from some past Dark Matter Day events can be found here:… More »
Fermilab employees, users and affiliates are invited to take part in an exciting moment for astronomy: the First Look livestream from the Vera C. Rubin Observatory — June 23, 2025 at 10 a.m. US CDT. Watch from your own device or join an in-person watch party in the WH8XO Hornet’s Nest (capacity: 60 people). This is a unique opportunity… More »
Fermilab CPC Scientist Alex Drlica-Wagner was selected as a 2024 Fellow of the American Physical Society (APS) for “For critical contributions to observational cosmology in DES, DELVE, and LSST, including groundbreaking work in dark matter science with these surveys and leading the implementation of ultra-low noise skipper-CCD in astronomical instrumentation, and for mentoring the next… More »
A new paper by the SuperCDMS collaboration places improved constraints on dark matter with a small array of cryogenic detectors (named HVeV). These detectors were operated in the NEXUS underground test stand, which is situated 100 meters underground in the Fermilab NuMI hall. The data revealed a background that was time-correlated between detectors (shown… More »
The 9.4T MRI magnet that is planned to be used by the ADMX-EFR experiment was delivered from the University of Illinois Chicago and lowered into the hall at PW8. The safe and successful operation was a combined effort of the particle physics directorate; environment, safety and health division; security and emergency management division. The magnet may also… More »
A team led by the Fermilab CCD Group performed the first on-sky demonstration using Skipper CCDs on the SOAR Telescope in Chile. This demonstration helps retire perceived risks for using this technology in future cosmology experiments recommended by the P5 Report such as DESI-II and Spec-S5. This project was a collaborative effort from Fermilab, UChicago,… More »
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 »
