The Dark Energy Survey collaboration has created the largest ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of over 7 billion light years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe, the standard cosmological model. Nevertheless, there remain hints from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.

DESI will capture and study the light from tens of millions of galaxies and other distant objects to better understand our universe and the properties of dark energy. The formal start of DESI’s five-year survey follows a four-month trial run of its custom instrumentation that captured 4-million spectra of galaxies — more than the combined output of all previous spectroscopic surveys. Fermilab has contributed multiple components to the international collaboration led by Berkeley Lab.

The Science and Technology Facilities Council, or STFC, has signed an agreement with Fermi National Accelerator Laboratory, in the United States, designating how the two organizations will collaborate to build one of the world’s most powerful linear accelerators.

The first baby bison of the season was born in the morning on April 26, 2021.

The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment of the same name performed at Brookhaven National Laboratory. Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete. One potential explanation would be the existence of undiscovered particles or forces.

Fermilab gives a sendoff to the final superconducting component for the LCLS-II particle accelerator at SLAC National Accelerator Laboratory in California. LCLS-II will be the world’s brightest and fastest X-ray laser. A partnership of particle accelerator technology, materials science, cryogenics and energy science, LCLS-II exemplifies cross-disciplinary collaboration across DOE national laboratories.

The international collaboration, including Fermilab, the National Center for Supercomputing Applications, NOIRLab and others, releases a massive, public collection of astronomical data and calibrated images from six years of surveys. This data release is one of the largest astronomical catalogs issued to date.

The U.S. Department of Energy has formally approved the scope, schedule and cost of the PIP-II project at Fermilab. The PIP-II accelerator will become the heart of Fermilab’s upgraded accelerator complex, delivering more powerful proton beams to the lab’s experiments and enabling deeper probes of the fundamental constituents of the universe.

A joint team of researchers at Fermilab and partner institutions have achieved quantum teleportation, teleporting information over a distance of 44 kilometers. The remarkable achievement supports the premise that scientists and engineers can build a workable and high-fidelity quantum network using practical devices.

Fermilab joins the global celebration of Dark Matter Day. Hear from Fermilab scientists during a special webinar on Saturday, Oct. 31, at 1 p.m. CT. Take a virtual tour of the lab’s dark matter experiments and detectors, and learn how Fermilab is helping answer questions about the mysterious stuff that makes up 25% of our universe.
