From UChicago News, Feb. 12, 2021: Fermilab scientist Yuanyuan Zhang discusses the implications of the studies she led on intracluster light using Dark Energy Survey data, which may include a new way of measuring dark matter.
From Universe Today, Feb. 3, 2021: Recent published results from the Dark Energy Survey point to intracluster light — feeble light from rogue stars that don’t belong to a galaxy — as a potential pathway to measure dark matter. Fermilab scientist Yuanyuan Zhang contextualizes the findings.
From Super Interessante, Jan. 31, 2021: A team of researchers from Fermilab and the National Observatory in Brazil used the light of solitary stars to calculate the mass of some of the largest structures in the cosmos — galaxy clusters. In addition to taking the most detailed measurement ever published of intracluster light, the team’s new method of measurement can help further investigate dark matter.
From Mission Unstoppable, Jan. 26, 2021: Fermilab scientist Jessica Esquivel explains how light particles work with makeup to create a look.
The motion of light depends crucially on the material in which it is traveling. When light passes from one medium to another, an unexpected thing happens: The direction of travel changes. There are many explanations out there for why this happens, and many of those explanations are wrong. In this 14-minute video, Fermilab scientist Don Lincoln explains the reason.
