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.
Fermilab is America’s particle physics and accelerator laboratory. Our vision is to solve the mysteries of matter, energy, space and time for the benefit of all.
Physicists achieve significant improvement in spotting accelerator-produced neutrinos in a cosmic haystack
Ground-breaking image reconstruction and analysis algorithms developed for surface-based MicroBooNE detector filter out cosmic ray tracks to pinpoint elusive neutrino interactions with unprecedented clarity.
Joint appointment at JGU and Fermilab: Alfons Weber is JGU’s new W3 Professor of Experimental Particle Physics
Alfons Weber has achieved full professorship teaching Experimental Particle Physics at Johannes Gutenberg University Mainz. His joint appointment at JGU and Fermilab represents the expansion of PRISMA+ neutrino physics research program.
The DOE’s Office of Science has selected two Fermilab scientists to receive the 2021 DOE Early Career Research Award, now in its 12th year. Farah Fahim and Brian Nord have received the prestigious award, which is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early years.
How do you build a ship in a bottle? Everything necessary to construct the enormous Fermilab-hosted international Deep Underground Neutrino Experiment must fit down a narrow, mile-deep shaft cut through solid rock. Contractors have started the months-long process of disassembling excavation equipment and lowering it underground.
The ICARUS detector, part of Fermilab’s Short-Baseline Neutrino Program, will officially start its hunt for elusive sterile neutrinos this fall. The international collaboration led by Nobel laureate Carlo Rubbia successfully brought the detector online and is now collecting test data and making final improvements.
Fermilab in the news
From CERN, June 15, 2021: A new study shows a class of new unknown particles that could account for the muon’s magnetism, known as leptoquarks, also affects the Higgs boson’s transformation into muons.
From the Dallas Morning News, June 13, 2021: The results of the April 7 Muon g-2 result strongly disagreed with the standard model and it is incumbent upon us now to explain this observation, writes Stephen Sekula, chair of physics and an associate professor of experimental particle physics at Southern Methodist University.
From Kathimerini (Greece), June 14, 2021: A multinational team of 400 researchers from 25 research centers in seven countries announced the results of the DES study that looked at 226 million galaxies and thousands of supernova explosions. The DES measurements, like those of other similar galactic surveys, informed us that the current universe is less dense than our model predicts.
