Tufts/CfA/MIT Cosmology Seminar, at CfA: Gary Hinshaw, Goddard Space Flight Center Title: The Microwave Anisotropy Probe (MAP): A Mission to Map CMB Anisotropy Abstract: The Microwave Anisotropy Probe was recently selected by NASA to be one of the first Midex class missions to launch in ~2000. MAP will measure the anisotropy of the Cosmic Microwave Background (CMB) radiation with high sensitivity over the full sky with ~0.3 degree angular resolution. This data should allow cosmologists to infer a tremendous amount about the physics of the early universe, including the mechanism of structure formation. The data should, in turn, constrain many fundamental cosmological parameters. I will present an overview of the physics of CMB anisotropy and MAP's strategy for measuring it.
