Professor Graham Peaslee of the University of Notre Dame Department of Physics is featured on the newest "What Would You Fight For?" video. The University of Notre Dame’s award-winning “What Would You Fight For?” series showcases the work, scholarly achievements, and global impact of Notre Dame faculty, students, and alumni. These two-minute segments, each originally aired during a home football game broadcast on NBC, highlight the University’s proud moniker, the Fighting Irish, and tell the stories of the members of the Notre Dame family who fight to bring solutions to a world in need.…

Erika Holmbeck, fifth-year graduate student in the Theoretical Nuclear Astrophysics and Galactic Archaeology groups of Professors Rebecca Surman and Timothy Beers, won the “Best Poster Award” for her work on Characterizing r-Process Sites Through Actinide Production…

After successfully achieving “first light,” capturing a beam of starlight filtered through the telescope’s adaptive optics system, the team discovered what was thought to be a singular star was actually a previously unidentified binary star system.

A team of researchers and undergraduate students at Nuclear Science Laboratory, Department of Physics at Notre Dame, published an article in the Applied Surface Science journal on the characterization of a set of Roman denarii, ranging from 136 BCE to 240 CE. The work presents results of macro, micro, and nanoscale surface characterization of coins using several different X-ray based spectroscopic and electron microscopy methods. This enabled the surface, the subsurface, and volume composition of these coins to be probed to better understand their production techniques, surface treatment methods, and corrosion patterns. The results also provide evidence that a particular surface treatment method, amalgam silvering, had been used to make authentic Roman coins as early as the third century CE.…
