ITHACA, N.Y. - Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy s Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation. There is uncertainty on the formation of stars within galaxies that theoretical models are unable to predict, said lead author Stefania Amodeo, a Cornell postdoctoral researcher in astronomy in the College of Arts and Sciences, who now conducts research at the Observatory of Strasbourg, France. With this work, we are providing tests for galaxy formation models to comprehend galaxy and star formation.
