This Project Grant from the National Science Foundation's Division of Astronomical Sciences, under the Mathematical and Physical Sciences program (CFDA 47.049), provides $234,319 to Penn State University from September 1, 2022 through August 31, 2025. The funding supports collaborative research between Penn State University and Vanderbilt University to conduct the benchmark measurement of quasar spectroscopic variability and implications for supermassive black hole binaries and changing-look quasars. Specifically, the researchers will leverage brightness changes in approximately 5,000 quasars observed spectroscopically more than once by the Sloan Digital Sky Survey to measure parameters of the broad H-beta line and their multi-year variability. This will enable statistical modeling of regular quasar variability to define searches for exotic sources like supermassive black hole binaries and changing-look quasars exhibiting unexpected behavior. Outreach activities include a data mining workshop for students and astronomy exercises using the Zooniverse platform. The award advances the goals of the NSF's "Windows on the Universe" research area.
