BICEP2
(Background Imaging of Cosmic Extragalactic Polarization)
(survey to measure the polarization of the CMB)
BICEP2 was a survey of CMB polarization
carried out at the South Pole Station, which is
a follow-on to an earlier survey called BICEP (for
Background Imaging of Cosmic Extragalactic Polarization).
The Keck Array and BICEP3 are follow-on surveys/telescopes
at the South Pole pursuing the same goals, and
the BICEP Array is being deployed as a follow-on to the Keck Array.
The terms also refer to the survey-specific telescopes used.
It was announced in early 2014 that BICEP2 detected
B-mode (polarization modes) gravitational waves from the
early universe, offering evidence of inflation,
but further analysis concluded that
dust within the Milky Way
could produce such a signal,
so the observation was inconclusive.
