Atacama B-Mode Search
(ABS)
(2012-2014 survey of the CMB)
The Atacama B-Mode Search (ABS) was an astronomical survey
of the cosmic microwave background (CMB) in search of B-mode CMB polarization,
carried out from 2012 to 2014 on a special-purpose telescope
(ABS telescope) operating on the Atacama Plateau,
located at the same site as the Atacama Cosmology Telescope (ACT). The survey had
the nominal goal of discovering B-modes due to inflationary
gravitational waves, but realistically was a test of equipment and techniques
and a source of data for combined analysis (cross-correlations)
and to strengthen existing conclusions.
