The Rise and Fall of Core-Collapse Supernovae

July 2, 2015 Tags: Edison, NERSC

Few events in the cosmos are as powerful as the explosion of a massive star in a supernova. For several weeks, the brightness of that single event can rival that of an entire galaxy. As a result, supernovae of various types are often used as "standard candles" in determining the size and expansion rate of a universe powered by dark energy. Despite decades of research, however, understanding the explosion mechanisms of supernovae remains among the great challenges of astrophysics—in… Read More »

Spiraling Laser Pulses Could Change Nature of Graphene

June 8, 2015

A new study that involved large-scale simulations run at NERSC predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.

Meraculous: Deciphering the ‘Book of Life’ With Supercomputers

June 1, 2015 Tags: CRD, NERSC

A team of scientists from Berkeley Lab, JGI and UC Berkeley, simplified and sped up genome assembly, reducing a months-long process to mere minutes. This was primarily achieved by “parallelizing” the code to harness the processing power of supercomputers, such as NERSC’s Edison system. Read More »

Supernova Hunting 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 »
