The CMB and Galactic Microwave Absolute Spectrum:. Science and Measurement with Arcade 2
Abstract
Beyond spatial anisotropy and polarization, a third type of structure in the Cosmic Microwave Background radiation, that of deviations in the overall absolute intensity versus frequency spectrum from a blackbody form, encodes additional important cosmological and astrophysical information, and remains inconclusively studied. This article discusses the ARCADE 2 project, the current balloon-based experimental effort to measure the absolute radiometric temperature of the CMB and Galactic microwave emission in the range from 3 to 90 GHz.
