Yuanyuan Su joined the University of Kentucky as an assistant professor of astronomy in 2019 after being a postdoc at the Harvard-Smithsonian Center for Astrophysics.
She is originally from Sichuan, China, the hometown of giant pandas. Su received her Ph.D. from the University of Alabama and went on to a postdoc in California before moving to Harvard.
Her primary research interest lies in clusters of galaxies. They are the largest gravitationally bound objects in the universe, containing thousands of galaxies that are held together by dark matter. The space between galaxies is filled with a very diffuse gas, the so-called “intracluster medium."
This gas is so hot that it radiates in X-rays but is undetectable at visual wavelengths. Su and her colleagues use space-based telescopes to observe galaxy clusters since the Earth's atmosphere absorbs X-rays.
