Researchers modeled for the first time faint supernovae of metal-free first stars, which yielded carbon-enhanced abundance patterns through the mixing and fallback of the ejected bits.

Scientists Take A Peek At Earliest Huge Black Holes In The Universe


Jan 23, 2019

A team of international scientists have investigated the birth of supermassive black holes in the early universe and found a new mechanism that might have triggered their formation: the rapid growth of dark matter halos.

NCSA Wins Best Visualization Award at Supercomputing ‘17


Nov 20, 2017

Director, Donna Cox of the Advanced Visualization Lab at the National Center for Supercomputing Applications (NCSA) at the University of Illinois took home the Best Scientific Visualization and Data Analytics Showcase Award at SC 17 in Denver. The visualizations were created by Donna Cox, Robert Patterson, Stuart A. Levy, Jeffrey D. Carpenter, AJ Christensen and Kalina M. Borkiewicz. The scientific simulation was run on the Blue Waters supercomputer by Michael Norman & Hao Xu, UC San Diego; Brian O’Shea, Michigan State U.; John Wise, Georgia Tech; Kyungjin Ahn, Chosun U.

Building blocks


Oct 20, 2015

Why do we care what happened 13 billion years ago? A bold lead question for an interview with an astrophysicist looking at the early universe, but one that doesn’t seem to faze Brian O’Shea. The Michigan State University professor just smiles across the Skype connection and then chuckles. ... O’Shea is no stranger to supercomputing or NCSA, dating back to his days as a student at the University of Illinois at Urbana-Champaign. As leader of a Petascale Computing Resource Allocations (PRAC) team that includes co-principal investigator Michael Norman and Hao Xu at the University of California, San Diego, John Wise of Georgia Tech, and Britton Smith of the University of Edinburgh, O’Shea’s been able to explore early galaxy formation and evolution. The team has published more than 16 papers, primarily in the Astrophysical Journal.

There May Be Nowhere Near the Number of Galaxies We Thought There Were


Jul 2, 2015

It looks like we might have overestimated how many neighbors we have. New predictions show that the universe might be an emptier place than we imagined. Since the Hubble launched, we’ve been seeing stunning image of the crowded universe. Most of the images come accompanied by assurances that what we see in the images is just the start. Astronomers have been excitedly guessing at the amount of faint, distant galaxies that they can’t see. Lurkers surely outnumbered visible galaxies. New simulations done on Blue Waters, a supercomputer at the National Center for Supercomputing Applications indicate that that isn’t the case.

Blue Waters simulations suggest there are fewer faint galaxies than expected


Jul 1, 2015

There may be far fewer galaxies further out in the Universe than might be expected, suggests a new study based on simulations conducted using the Blue Waters supercomputer at the National Center for Supercomputing Applications, with resulting data transferred to SDSC Cloud at the San Diego Supercomputer Center at the University of California, San Diego, for future analysis. The study, published this week in the Astrophysical Journal Letters, shows the first results from the Renaissance Simulations, a suite of extremely high-resolution adaptive mesh refinement (AMR) calculations of high redshift galaxy formation. "Our work suggests that there are far fewer faint galaxies than one could previously infer," said principal investigator and lead author Brian W. O'Shea, an associate professor at Michigan State University with a joint appointment in the Department of Computational Mathematics, Science and Engineering; the Department of Physics and Astronomy; and the National Superconducting Cyclotron Laboratory.
