A multi-institutional study led by University of California, San Diego (UCSD) researchers developed high-resolution computer simulations of galactic clusters. The RomulusC models apply black-hole physics to examine the molecular gas within and enclosing the intracluster medium, using ultraviolet light from quasars shining through the gas to explore the clusters in greater detail. The researchers used the Trident software tool to render synthetic absorption line spectra into a realistic spectrum for direct comparison to existing observations. The scientists also tapped four supercomputers, including UCSD’s Comet system, to model the clusters. Said the University of Washington’s Iryna Butsky, “Simulations are extremely important in being able to make progress in theoretical work.”
