Intensity mapping is an emerging approach that surveys the cumulative surface brightness of redshifted line radiation. It has parallels with both CMB and large-scale structure surveys, and a wide range of scientific goals from precision cosmology to galaxy evolution. I will describe a pathfinder survey for 21 cm mapping at z~1 using the Green Bank Telescope. A combined analysis of the 21 cm...   More >
