CMB

Last week we published new results from the BICEP1 Cosmic Microwave Background (CMB) polarization experiment. (Disclaimer: I'm a coauthor of the paper.) BICEP1 is the first in a series of experiments at the South Pole searching for the signal of cosmological Inflation in the CMB. BICEP1 took data in 2006--2008, but this is the first result to include all three years of data.

Last week, members of the South Pole Telescope (SPT) collaboration reported the first detection of B-mode polarization in the Cosmic Microwave Background (CMB). Scientists have been searching for B-mode polarization for over a decade because it offers an opportunity to study all the matter in the Universe and the cause of the Big Bang.
