Cosmic Microwave Background Polarization| Cosmic Microwave Background Polarization |
In General
> s.a. observational cosmology [parameters]; dark matter.
* Values:
* Linear polarization:
It is produced by Compton scattering.
* Circular polarization:
It is produced during the propagation of polarized cmb photons through
regions of the large-scale structure containing magnetized relativistic
plasma, such as galaxy clusters.
* Significance: Related
to anisotropy, but it is a signature of the motion of the primordial
seeds that led to the large-scale structure observed today, and gives
a different combination of information on physical parameters, including
the presence of gravitational waves.

Detection
* 2002: Linear polarization
≈ 10−6 (DASI); Characterized
by Stokes parameters S0
or I = (Tx
+ Ty)/2,
S1 or Q
= (Tx
− Ty)/2,
S2 or U,
and S2 or
S3 or U.
* 2014: Announcement by BICEP Collaboration
of the detection of B modes, presumably produced by gravitational waves generated
by quantum fluctuations during inflation.
* BICEP: (Background Imaging of Cosmic
Extragalactic Polarization): An experiment that took data at the Amundsen-Scott South Pole
Station from 2010 to 2012, designed to measure the polarization of the cosmic microwave background;
> see website.
* Other experiments: Planck spacecraft, Atacama B-mode Search.
