Associate Professor of Physics and Astronomy Rebecca Koopmann ’89 recently presented a paper at the “Galaxy Wars: Stellar Populations and Star Formation in Interacting Galaxies” Conference held at East Tennessee State University in Johnson City, Tenn. “ALFALFA HI Content and Star Formation in Virgo Cluster Early-Type Dwarfs” describes Koopmann’s research on the hydrogen gas contents of nearby galaxies as revealed by the ALFALFA (Arecibo Legacy Fast ALFA) survey using the Arecibo telescope in Puerto Rico. Koopmann also hosted an NSF-sponsored Undergraduate ALFALFA Team group meeting at Union for faculty and students in July. The meeting drew participants from Siena and Skidmore colleges to campus, while participants from Cornell University, Georgia Southern University, Humboldt State University and Lafayette College joined via teleconference. Students from each institution presented summaries of ALFALFA research progress during the summer. SreyNoch Chin ’12 presented Union’s progress report.
