Successful tests pave the way for Fermilab’s next-generation particle accelerator

This spring testing wrapped up at the PIP-II Injector Test Facility, or PIP2IT. The successful outcome paves the way for the construction of PIP-II, a new particle accelerator that will power record-breaking neutrino beams and drive a broad physics research program at Fermilab for the next 50 years.

A minute with Aleksandra Ćiprijanović, astrophysicist

Whether in Serbia or Chicago, Fermilab postdoctoral researcher Aleksandra Ćiprijanović is working to unlock the secrets of the night sky. As a member of the Deep Skies Lab, an international collaboration of physicists, she’s figuring out how to use artificial intelligence and machine learning to better handle the huge amounts of data needed for discovery science.

Dark Energy Survey releases most precise look at the universe’s evolution

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.
