A new economic impact study shows the growing positive effects on economies in the U.S. through operations conducted by Fermi National Accelerator Laboratory. In Illinois and South Dakota, positive ripple effects from Fermilab spending contributed $1.6 billion in economic output during fiscal year 2022 and supported 7,242 jobs.
The Dark Energy Survey has measured the BAO scale when the universe was half its present age with an accuracy of 2%, the most accurate determination yet at such an early epoch. It is the first time an imaging-only measurement is competitive with large spectroscopy campaigns specifically designed to detect this signal.
In the culmination of a decade’s worth of effort, the DES collaboration of scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.
