Supercomputer Simulations Reveal Details of Galaxy Clusters
Jan 24, 2020
Inspired by the science fiction of the spacefaring Romulans of Star Trek, astrophysicists have developed cosmological computer simulations called RomulusC, where the ‘C’ stands for galaxy cluster. With a focus on black hole physics, RomulusC has produced some of the highest resolution simulations ever of galaxy clusters, which can contain hundreds or even thousands of galaxies. “We find that there’s a substantial amount of this cool-warm gas in galaxy clusters,” said study co-author Iryna Butsky, a PhD Student at the University of Washington. “We see that this cool-warm gas traces at extremely different and complementary structures compared to the hot gas. And we also predict that this cool-warm component can be observed now with existing instruments like the Hubble Space Telescope mass spectrograph.” Researchers used the Comet supercomputer at the San Diego Supercomputer Center (SCSC) at UC San Diego, the Stampede2 system at the Texas Advanced Computing Center (TACC), Blue Waters at the National Center for Supercomputing Applications (NCSA) and NASA’s Pleiades system.

CalTech Researcher Uses Blue Waters to Model Galactic Atmospheres
Feb 11, 2019
By employing their Enhanced Halo Resolution modeling technique on Blue Waters, one of the most powerful supercomputers in the world, Hummels and his research team are able to, more accurately than ever before, account for cool hydrogen gas that is spewed into galactic outskirts in vast quantities following galaxy formation.

Blue Waters Graduate Fellow: Iryna Butsky
Sep 19, 2016
I really enjoyed my research on galactic magnetic fields, and I wanted to pursue it further. I'm very interested in studying the contribution of cosmic rays to the turbulent dynamo which amplifies galactic magnetic fields. Cosmic rays are tricky to model in galaxy simulations and have thus oftentimes been ignored. However, they could be key to the explanation of the strength of observed field strengths.

Ten PhD students from across the country selected as Blue Waters Graduate Fellows
Apr 19, 2016
Ten outstanding computational science PhD students from across the country have been selected to receive Blue Waters Graduate Fellowships for 2016-2017. The fellowship program, now in its third year, provides substantial support and the opportunity to leverage the petascale power of National Center for Supercomputing Applications (NCSA) at the University of Illinois’s Blue Waters supercomputer to advance their research. The awards are made to outstanding PhD graduate students who have decided to incorporate high performance computing and data analysis into their research.
