Stacy Kim is a postdoctoral research associate in the astrophysics group at the Univeristy of Surrey. She received her Ph.D. from The Ohio State University in 2019, and her B.S. from the California Institute of Technology in 2013.
She is involved in the search for the particle identity of dark matter. Her work focuses on devising stronger tests on dark matter particle properties by tracing how they imprint themselves onto astrophysical structures. She has derived some of the strongest constraints to date on two dark matter properties: its ability reproduce the structural hierarchy of the universe down to low mass scales, and whether or not it obeys a new “dark” force that allows dark matter particles to exchange momentum. She is working to place even stronger constraints on these properties by searching for the smallest galaxies in the universe and laying the theoretical groundwork necessary to harness the tremendous statistical power promised by upcoming astronomical surveys.
Areas of specialism
Stacy Kim is working to develop new astrophysical tests for dark matter particle properties. She has studied the largest bound objects in the universe---galaxy clusters---to test for signs of a new dark force, as well as the smallest known galaxies to constrain the mass of the dark matter particle. She is currently working on developing a new model that predicts how observable properties of dwarf galaxies change under different dark matter models.
