Quasars are most commonly found with redshifts around 2, indicating they were most active when the universe was roughly a quarter of its current age. This period is often referred to as the "quasar epoch" or "peak quasar era," which corresponds to a time when these supermassive black holes were undergoing rapid growth and were highly luminous.
