Hunting Supernova with Supercomputers
Using a “roadmap” of theoretical calculations and supercomputer simulations performed at NERSC by Berkeley Lab’s Daniel Kasen, astronomers observed for the first time a flash of light caused by a supernova slamming into a nearby star, allowing them to determine the stellar system from which the supernova was born. This finding confirms one of two competing theories about the birth of Type Ia supernovae. Read More »
