Mode Effects

Inflationary cosmology is successful in explaining a number of outstanding cosmological issues, including the flatness, the horizon and the relic issues. More spectacular is the experimental confirmation of the structure as arising from the inflationary quantum fluctuations. However, the physics in the inflationary era is unclear. Polarization observations of cosmic microwave background (CMB) missions may detect the tensor mode effects of inflationary gravitational waves (GWs) and give an energy scale of inflation. To probe the inflationary physics, direct observation of GWs generated in the inflationary era is needed. In this essay, we advocate that the direct observation of these GWs with sensitivity down to Ω GW ~ 10-23 is possible using the presently projected technology development if the foreground could be separated.

Cosmic Microwave Background Polarization

AbstractBicep was a telescope designed to probe the polarization of the cosmic microwave background (CMB) for the signature of gravitational waves produced during the epoch of inflation. The instrument was developed by a team of scientists from Caltech/JPL, UC Berkeley, and UC San Diego. It was installed at the South Pole in November 2005 and the CMB observations were conducted from February to November each year with one winter-over scientist responsible for operating and maintaining the instrument. Taking advantage of the excellent atmospheric conditions at the South Pole, we mapped 2% of the sky at 100 and 150 GHz. We completed 3 years of observations from 2006 to 2008, mapping the CMB polarization anisotropy at degree angular scales with unprecedented sensitivity. In 2010, a next generation instrument, Bicep2, will be installed on the existing telescope mount for an even deeper survey.

Astrophysicists search the cosmic microwave background for B-mode polarization. Sometimes they get overexcited. Gravitational waves discovered? Or not. Umberto Cannella takes a look at the Background Imaging of Cosmic Extragalactic Polarization (BICEP2) experiment.
