The intrinsic B-mode polarisation of the cosmic microwave background [PDF]
, 2014 . We estimate the B-polarisation induced in the Cosmic Microwave Background by the non-linear evolution of density perturbations. Using the second-order Boltzmann code SONG, our analysis incorporates, for the first time, all physical effects at ...

Observation of Cosmic Microwave Background Polarization with BICEP [PDF]
, 2009 Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...

THE COSMIC MICROWAVE BACKGROUND RADIATION* [PDF]
Annals of the New York Academy of Sciences, 1981 Because angular anisotropies and spectral distortions of the cosmic microwave background radiation are judged to be inevitable at some level, in a realistic cosmological model, the evidence for spectral distortions and its theoretical implications are described.

The SPIDER CMB Polarimeter [PDF]
, 2012 SPIDER is a balloon-borne millimeter-wave telescope designed to study the polarization of the Cosmic Microwave Background (CMB). SPIDER will map 10% of the full sky with degree-scale beams to search for the distinctive inflationary gravitational wave ...

Testing Cosmic Microwave Background Anomalies in E-mode Polarization with Current and Future Data
The Astrophysical Journal, 2023 In this paper, we explore the power of the cosmic microwave background (CMB) polarization ( E -mode) data to corroborate four potential anomalies in CMB temperature data: the lack of large angular-scale correlations, the alignment of the quadrupole and ...

Long-range correlation in cosmic microwave background radiation [PDF]
Physical Review E, 2011 We investigate the statistical anisotropy and Gaussianity of temperature fluctuations of Cosmic Microwave Background radiation (CMB) data from {\it Wilkinson Microwave Anisotropy Probe} survey, using the multifractal detrended fluctuation analysis, rescaled range and scaled windowed variance methods.

CMB as a Probe of New Physics and Old Times [PDF]
, 2013 Cosmic birefringence (CB)---a rotation of photon-polarization plane in vacuum---is a generic signature of new scalar fields that could provide dark energy. Previously, WMAP observations excluded a uniform CB-rotation angle larger than a degree.

The Astrophysical Journal, 2023 The exquisitely measured maps of fluctuations in the cosmic microwave background (CMB) present the possibility of systematically testing the principle of statistical isotropy of the Universe. A systematic approach based on strong mathematical formulation
