How Parallel Processing Solves Our Biggest Computational Problems


Nov 6, 2019

Researchers solved a four-decade-old mystery, proving that the innermost part of matter that orbits, then collapses into, black holes aligns with those black holes; Last year, researchers at U of I’s Department of Natural Resources and Environmental Sciences topped the feds’ industry-standard forecast by incorporating more data which proved more accurate by nearly five bushels per acre.

Most-detailed-ever simulations of black hole solve longstanding mystery


Jun 5, 2019

An international team has constructed the most detailed, highest resolution simulation of a black hole to date. The simulation proves theoretical predictions about the nature of accretion disks -- the matter that orbits and eventually falls into a black hole -- that have never before been seen.

Black hole breakthrough: new insight into mysterious jets


Jan 9, 2018

Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the behavior of relativistic jets that shoot from black holes, extending outward across millions of light years.
