Date: November 3, 2008 (Monday) Time: 3:30 pm EST (refreshments at 3:20 pm) Place: Green Bank Auditorium (Video: CV-AUD/AOC-AUD/TUC-N525) Speaker: Tony Remijan, NRAO Title: "NSF Center for Chemistry of the Universe and the future of Astrochemistry at UVa and NRAO" Abstract: The recently funded NSF Center for Chemistry of the Universe will assemble a group of researchers from across the United States to investigate and understand the chemical processes that control the synthesis of molecules in the interstellar medium. The chemistry occurring under the unique conditions of the interstellar medium produces the initial molecular starting materials for solar system formation. This chemistry, which produces a surprisingly rich set of common organic molecules along with more exotic reactive species, also supplies the molecules in meteorites and comets that may deliver the building blocks of life to young planets. The Center will place chemistry at the center of research efforts to describe the molecular composition of the universe. In this model, the powerful new tools being developed for observational astronomy will be used to test chemical hypotheses about novel reaction mechanisms that include photochemistry by extreme ultraviolet radiation on the surfaces of nanoscale solids and gas-phase chemistry of ions and radicals under low collision rates and at ultracold temperatures. These unique reaction conditions will allow the Center to explore new types of chemistry that go beyond the usual boundaries imposed by terrestrial conditions. The Center will establish connections between fields such as combustion chemistry, atmospheric chemistry, and materials processing that share the theme of "chemistry under extreme conditions". At the center of these new experiments, laboratory measurements and theoretical models will be NRAO instrumentation including the GBT, eVLA and ALMA. In this presentation I will discuss the make-up of the center and its participants and what the expectations of each NRAO instrument will be in the next decade of astrochemistry research.
