Cosmic Microwave Background Mission Design and Analysis

This research group focuses on the design and implementation of the E and B EXperiment (EBEX), a NASA-funded balloon-borne polarimeter designed to measure the polarization of the cosmic microwave background and foreground thermal emission from dust at high galactic latitude. EBEX completed an engineering test flight from Ft. Sumner, New Mexico, in June 2009, and is in preparation for an upcoming Antarctic long-duration balloon flight. These measurements promise to yield strong constraints on models of the origin and evolution of the universe. Instrumental design efforts and development of the data analysis pipeline for EBEX have required significant computing power, and development on the pipeline tools is ongoing. The researchers have also used MSI resources to continue data analysis for the MAXIPOL mission, the predecessor to EBEX.
