    From Astronomy to Acoustics and Back Again Through Undergraduate Research

    After earning my PhD in physical acoustics at Ole Miss and a number of years at institutions almost exclusively devoted to teaching, I returned to active research by joining a team of astrophysicists working on projects that emphasize undergraduate research in observational cosmology. I will discuss the ways undergraduates have been involved in cutting-edge research via this team approach and overview the science behind the projects.

    Our emphasis has been on HI (21 cm) radio surveys of nearby galaxies. These include the completed ALFALFA blind survey of the nearby universe, and the current targeted Arecibo Pisces-Perseus Supercluster Survey (APPSS) which attempts to detect dark matter-driven infall of galaxies onto a nearby supercluster filament. I will include a discussion of the observing strategies and the planned use of the baryonic Tully-Fisher relation to separate the effects of cosmic expansion and local peculiar velocities using Bayesian statistical methods.
