Gas and Stars in EAGLE Simulation (IMAGE) Durham University Caption Gas and stars in a slice of the EAGLE simulations at the present day. The intensity shows the gas density, while the color encodes the gas temperature. Researchers used the EAGLE simulations to predict the rate at which gravitational waves caused by collisions between supermassive black holes might be detected.
