Nathan W. C. Leigh is Professor of Astrophysics at the Universidad de Concepcion in Chile and Research Scientist at the American Museum of Natural History. He works as a theorist using a combination of computational simulations and analytic methods. His primary research interests include gravitational dynamics, chaos, the three-body problem, black holes, star cluster evolution, and both single and binary star evolution. He has worked at the European Space Agency, the American Museum of Natural History, the Flatiron Institute, and many more.Aaron Geller holds a PhD in Astrophysics. He is Research Faculty Member at Northwestern University’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) and Lead Data Scientist within Northwestern IT Research Computing and Data Services (RCDS), USA. His research combines multi-wavelength observations, including stellar photometry and spectroscopy, with numerical simulations, often incorporating advanced statistical, data science, and computational techniques.Taeho Ryu is Professor of Astrophysics and JILA Associate Fellow at the University of Colorado, Boulder, USA. He is a theoretical astrophysicist studying interactions between black holes and their surroundings, as well as interactions between stars in various environments, which can lead to the generation of electromagnetic radiation and gravitational waves. His expertise lies in numerical modeling of short-lived, observable astronomical phenomena.
