Supercomputer provides new suite of Lyman-α forest simulations for illustrating large-scale structure of universe

Like a celestial beacon, distant quasars make the brightest light in the universe. They emit more light than our entire Milky Way galaxy. The light comes from matter ripped apart as it is swallowed by a supermassive black hole. Cosmological parameters are important numerical constraints astronomers use to trace the evolution of the entire universe billions of years after the Big Bang.
