Simulations of the Formation, Evolution, and Clustering of Early Cosmic Strucure

We have performed large-scale computer simulations of the formation of the first stars in the universe. Our simulations provide a complete picture of how a star is formed out of tiny density fluctuations left over from the Big Bang. The characteristic mass of the first stars is determined, through large-scale simulations on a first principle basis, to be several tens times that of the sun. We provide detailed forecast for observations of the signature of the first stars in radio to infrared wavelengths.
