Jonathan Pober, Brown University, Putting the Cosmology in "21 cm Cosmology"
KICP seminar: February 12 @ 12 PM, ERC 401
21 cm cosmology -- the concept of using radio telescopes to observe the highly redshifted 21 cm line of neutral hydrogen on cosmological scales -- is a field on the verge of a breakthrough. The first generation of 21 cm cosmology experiments (LOFAR, MWA, and PAPER, among others) have been operating for several years, and first results at the level of design sensitivity are potentially forthcoming.
