Physics and Astronomy summer research students displayed the results of their projects in a poster session on Thursday, Sept. 13.
Scott LaBrake, Senior Lecturer and Accelerator Manager in the Department of Physics & Astronomy, presented a poster titled “Construction of a Scattering Chamber for Ion-Beam Analysis of Environmental Materials in Undergraduate Physics Research” at CAARI 2012 the 22nd International Conference on the Applications of Accelerators in Research and Industry in Fort Worth, Texas, in August. A paper of the same title was submitted for the conference proceedings. Michael Vineyard, the Frank and Marie Louise Bailey Professor of Physics, and three Union students were co-authors on the paper.
Prof. Koopmann organized and hosted an international group of astronomers for the Star Formation and Gas Reservoirs in Nearby Groups and Clusters
Conference from July 8-11, 2012. Prof. Koopmann received funding from the Skidmore Union Network (NSF ADVANCE grant, PI Brenda Johnson) to gather an international group of astrophysicists to discuss the latest results on the evolution of galaxies relatively near the Milky Way. The meeting focused on the observed star formation properties and gas content (the raw material for star formation) of galaxies in nearby relatively high density regions (groups and clusters), and the current theoretical understanding of the dominant physical mechanisms at work in the conversion of their gas to stars. The invited speakers were Michael Balogh (U. Waterloo), Greg Bryan (Columbia U.), Henry Ferguson (Space Telescope Science Institute), Christine Jones (Harvard U.), Martha Haynes (Cornell U.), Robert Kennicutt (Cambridge Institute of Astronomy, UK), and Ann Zabludoff (U. Arizona).
There were 73 attendees, including ~30 from international institutions (including Argentina, Austria, Australia, Belgium, Canada, Chile, Germany, Italy, Korea, Russia, South Africa, Spain, and Switzerland). 14 were undergraduates, including 2 Union students: Halley Darling, ’13, and Lucas Viani, ’14.
A well-known attendee was Neil deGrasse Tyson, whose research interests include unusually active star-formation in galaxies in dense environments. He spent time with student attendees and interacted and posed for pictures with Union summer research students who recognized him during the lunch in Wold Atrium.
Halley Darling, ’13, and Lucas Viani, ’14, each presented posters during the conference about their multi-year research projects with Koopmann on the gas and star formation properties of a nearby group of galaxies.
Many Union staff helped with the conference. Special thanks to Colleen Palleschi, Halley Darling, Lucas Viani, Scott LaBrake, Paul Debiase,

Physics and Astronomy majors Halley Darling, ’13, Lucas Viani, ’14, and Rachel Almovodar, ’15, recently observed at the Arecibo Telescope in Puerto Rico with Physics & Astronomy Professor Rebecca Koopmann, ’89. The team carried out a 4-night observing run to record radio emission from hydrogen gas in galaxies located up to 750 million light-years away. The Arecibo telescope operates at radio wavelengths and is the world’s largest reflector, spanning more than 1,000 feet in diameter and with a surface area as big as 26 football fields.
The observations carried out by the Union team are part of the ongoing ALFALFA (Arecibo Legacy Fast ALFA, where ALFA i
s the name of the detector used in the observations) survey, a 7-year project headed by Riccardo Giovanelli at Cornell University, to census hydrogen-bearing galaxies in the local Universe. Among the targets were some of the smallest galaxies yet detected.
Funding for the trip was provided by Koopmann collaborative NSF “Undergraduate ALFALFA Team” grant with Colgate University and Georgia Southern University. The Union team also trained faculty and student colleagues from Hartwick College and St. Mary’s College of California in observing and data reduction techniques.
The trip was part of the Sophomore Scholar’s Project of Lucas Viani, ’14; he studied gas and star formation properties of a nearby gravitationally-bound group of galaxies.
Rachel Almodovar is from Puerto Rico – it was a childhood dream of hers to observe at Arecibo, an opportunity provided by Union! She wrote up her thoughts on observing at Arecibo on the ALFALFA blog at: http://alfalfasurvey.wordpress.com/2012/03/28/a-childhood-wish-come-true/
All three students will be working with Koopmann this summer on research related to the observing trip.
Associate Professor of Physics and Astronomy Rebecca Koopmann, ’89, organized the fifth annual NSF-sponsored ALFALFA (Arecibo Legacy Fast ALFA) Undergraduate Team Workshop at Arecibo Observatory in Puerto Rico January 16-18, 2012. The Arecibo Observatory is home to the 305-m diameter Arecibo telescope, the largest telescope in the world.
Lucas Viani, ’14, a Physics & Astronomy major, and Wyatt Smith accompanied Koopmann and a select group of 16 other undergraduate students and 11 faculty members from 14 colleges and universities across the United States. Together they conducted observing runs, toured the telescope, and learned about radio astronomy. Viani and Smith presented posters about their summer research 2012 projects with Koopmann.
Congratulations to the graduates of the class of 2011!

The Union College chapter of the Society of Physics Students was recognized as an outstanding chapter for 2010, one of just 50 chapters nationwide (out of more than 700 nationwide) given this award. Union was cited for “Extensive outreach, community service, and social activities.” This is the second year in a row that Union has earned this distinction.
Congratulations to all the SPS students whose hard work has made this possible.
Katelyn O’Brien, ’11, and Daniel Barringer, ’11, presented posters about their research at the 217th meeting of the American Astronomical Society meeting in Seattle, WA, in January.
The American Astronomical Society is the major organization of professional astronomers in North America.
Associate Professor of Physics and Astronomy Rebecca Koopmann, ’89, organized the fourth annual NSF-sponsored ALFALFA (Arecibo Legacy Fast ALFA) Undergraduate Team Workshop at Arecibo Observatory in Puerto Rico January 16-20, 2011. The Arecibo Observatory is home to the 305-m diameter Arecibo telescope, the largest telescope in the world.
Halley Darling, ’13, a Physics & Astronomy major, accompanied Koopmann and a select group of 16 other undergraduate students and 12 faculty members from 14 colleges and universities across the United States. Together they conducted observing runs, toured the telescope, and worked on group activities designed to model scientific collaborations.
As part of the workshop, Darling presented a poster about her Summer 2010 research project at Union (sponsored by NASA New York Space Grant). Entitled “ALFALFA HI Observations of the NGC 5846 Group of Galaxies,” the poster described the Union team’s research on environmental effects (such as gravitational interactions) on a concentration of galaxies. Ana Mikler, ’12, and SreyNoch Chin, ’12, were coauthors on the poster.
Darling used her new skills to help Koopmann conduct a remote observing run from her Union campus lab in Science and Engineering. Two first-year students, Lucas Viani ’14 and Alexandrea Safiq ’14, were enthusiastic participants. They can be seen steering the telescope on the ALFALFA blog.
The ALFALFA project, led by astronomers Riccardo Giovanelli and Martha Haynes of Cornell, is a multiyear survey of a large area of the sky at radio wavelengths appropriate for the detection of neutral hydrogen gas in other galaxies. It is expected that more than 30,000 galaxies out to a distance of 750 million light years will be detected by the survey.
