Supernovae, Dark Energy and the Accelerating Universe - a free public talk
Date and TimeMonday, February 27, 2012
7:00 PM - 9:00 PM
- Loosemore Auditorium - GVSU Pew Campus (downtown Grand Rapids)
A free public talk for students, teachers, parents, and the community-at-large.
Dr. Louis Strolger, who worked with the 2011 Nobel Prize winners in Physics
Supernovae—the explosions of stars—have been utilized to probe vast, cosmological distances, and have brought about some astonishing results. Evidence from supernovae have shown us that the cosmic expansion, set in motion by the Big Bang nearly 14 billion years ago, has been speeding up over the last 5 billion years-- an acceleration we attribute to a mysterious ``dark energy''. The quest to understand dark energy and ambitious surveys with powerful instruments (including the Hubble Space Telescope) are giving insights into the nature of the universe. Dr. Strolger will explore how the discovery of dark energy has marked an unprecedented change in our understanding of the cosmos, and now presents a fundamental challenge to the foundations of physics.
Dr. Strolger made important contributions to the study of dark energy with the three 2011 Nobel Physics laureates while serving as a postdoctoral researcher and has co-authored several seminal papers in astrophysics. He is the Chair of the Space Telescope Science Institute’s Users Committee and is a lead investigator in a project using the Hubble Space Telescope to probe dark energy in the first five billion years of the universe. He also serves as Chair of both the American Physical Society’s Committee on the Status of Minorities in Physics and the American Astronomical Society’s Committee on the Status of Minorities in Astronomy. He is currently an Associate Professor of Physics and Astronomy at Western Kentucky University.
