Primordial Non-Gaussianity in the Cosmic Microwave Background by Amit P. S. Yadav, Benjamin D. Wandelt

“…We discuss (1) theoretical predictions from inflationary models and their observational consequences in the cosmic microwave background (CMB) anisotropies; (2) CMB-based estimators for constraining primordial non-Gaussianity with an emphasis on bispectrum templates (3) current constraints on non-Gaussianity and what we can hope to achieve in the near future and (4) nonprimordial sources of non-Gaussianities in the CMB such as bispectrum due to second order effects, three way crosscorrelation between primary-lensing-secondary CMB, and possible instrumental effects.…”

Cosmic Strings and Their Induced Non-Gaussianities in the Cosmic Microwave Background by Christophe Ringeval

“…Motivated by the fact that cosmological perturbations of inflationary quantum origin were born Gaussian, the search for non-Gaussianities in the cosmic microwave background (CMB) anisotropies is considered as the privileged probe of nonlinear physics in the early universe. …”

The Asymmetry of the Cosmic Microwave Background Radiation as Signature of Local Lorentz Invariance Violation by Gianni Albertini, Fabio Cardone, Stefano Bellucci

“…The asymmetry of the two experiments is related to the asymmetry of the Cosmic Microwave Background Radiation (CMBR). As common directions of asymmetry are found in these three cases, a fundamental asymmetry of the interactions is suggested which can also shed new light on the question of symmetry breaking in the history of the Universe.…”
