Supercomputing How First Supernovae Altered Early Star Formation

Over at LBNL, Kathy Kincade writes that cosmologists are using supercomputers to study how heavy metals expelled from exploding supernovae helped the first stars in the universe regulate subsequent star formation. “In the early universe, the stars were massive and the radiation they emitted was very strong,” Chen explained. “So if you have this radiation before that star explodes and becomes a supernova, the radiation has already caused significant damage to the gas surrounding the star’s halo.”

“I think it’s a very interesting period for human cosmology because it’s a golden age in which every ten years we learn breathtaking new parts of the story. We have never before been able to do that in human history – to have the chance we have now to look at and understand the universe we live in.”
