[Asia Economy Reporter Hyunju Lee] Sejong University announced on the 6th that it has developed a high-resolution cosmological hydrodynamics simulation called 'Sejong Suite' in collaboration with Professor Graziano Rossi of the Department of Physics and Astronomy and the Cosmology Laboratory.

Sejong Suite is a set of over 300 high-resolution cosmological hydrodynamics simulations focusing on the dark regions appearing in the cosmic web structure at high redshift observed through the Lyman-alpha forest. The research was conducted with support from the National Supercomputing Center and the National Research Foundation of Korea. Sejong Suite accurately depicts the nonlinear evolution required in the Lyman-alpha forest and the complex baryonic effects on small scales. It also enables visualization of the presence of massive neutrinos and dark matter. Based on this achievement, Sejong University expects to interpret numerous Lyman-alpha forest data provided by baryon acoustic oscillation spectroscopic surveys and dark energy spectroscopic observation instruments.
