The American Astronomical Society (AAS) awarded David H. Weinberg, the Henry L. Cox Professor in Astronomy and Distinguished Professor of Mathematical and Physical Sciences, the Lancelot M. Berkeley New York Community Trust Prize for Meritorious Work in Astronomy. It recognizes “highly meritorious work in advancing the science of astronomy during the previous year.” Weinberg studies the large-scale structure of the universe, dark energy and dark matter, the formation and evolution of galaxies and quasars and the intergalactic medium. Weinberg was honored for leading contributions to SDSS-III, the third phase of the Sloan Digital Sky Survey, which has made dramatic advances in measuring the structure of the Milky Way galaxy and the history of the accelerating expansion of the universe.
