Fermilab features

A veteran administrator with a love of flowers and true crime, Maxine Hronek draws on three decades of Fermilab experience to keep the international Deep Underground Neutrino Experiment running smoothly behind the scenes — and remind people that science takes the efforts of a whole community of dedicated individuals.

Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists on the Dark Energy Survey, led by Fermilab, have made the most radially extended measurement of this light ever and have found new evidence that its distribution might point to the distribution of dark matter.

From working at the CIA to designing science facilities at Fermilab, Kate Sienkiewicz enjoys tackling complex problems. Currently, she oversees the team tasked with designing and building conventional facilities at the Long-Baseline Neutrino Facility near site for the international Deep Underground Neutrino Experiment — all with the overarching goal of understanding the universe.
