Steve Rodney, University of South Carolina, "Stellar Explosions, Strongly Lensed"
KICP seminar: December 4 @ 12PM
The Hubble Space Telescope Frontier Fields survey has been extending the reach of HST by targeting massive galaxy clusters that act as cosmic telescopes: using gravitational lensing to amplify the light of distant objects. This makes it possible to detect the explosions of stars that formed when the universe was less than a few billion years old.
