EXCERPT: A ripple in the outskirts of the Milky Way—and a hunch—led Rochester Institute of Technology astrophysicist Sukanya Chakrabarti to a previously undetected dwarf galaxy hidden under a veil of dark matter. Now Chakrabarti is refining her technique to uncover dwarf galaxies and understand dark matter by simulating the evolutionary histories of galactic disks, rich in atomic hydrogen, and their satellite populations. [...] Her research seeks to solve an astrophysical conundrum dubbed “the missing satellites problem,” in which theoretical simulations that predict an abundance of satellite galaxies are unsupported by observational data....
