Observational Evidence For Constant Gas Accretion Rate Since z = 5
, 2017 Star formation rate density (SFRD) has not been constant throughout the history of the Universe. The rate at which stars form greatly affects the evolution of the Universe, but the factors which drive SFRD evolution remain uncertain.
