Project title: Observing the Frequency of Mergers in Post-Starburst Galaxies

Department: Physics and Astronomy

Faculty supervisor: Dr. Sara Ellison

"Post starburst galaxies are defined as galaxies that have had star formation in the last billion years and then recently stopped forming stars. My research will select Post-Starburst galaxies from the Sloan Digital Sky Survey using a modern identification method and observe their morphologies to determine if they have recently merged with other another galaxy. I will then compare the merger frequency to a control sample and to sample of Post-Starburst galaxies selected using a more traditional method. The goal of this research is to quantify the relationship between mergers and Post-Starburst galaxies and to explore the different methods of identifying galaxies as Post-Starburst and classifying galaxies as mergers."
