However, this invaluable information is potentially screened, as not all of the observed non-Gaussianity is of primordial origin. Indeed, a bispectrum arises even for perfectly Gaussian initial conditions due to non-linear dynamics, such as CMB photons scattering off free electrons and propagating in an inhomogeneous Universe. Dr. Pettinari introduces the reader to this .intrinsic bispectrum. in a pedagogic way, building up from the standard model of cosmology and from cosmological perturbation theory, the tool cosmologists use to unravel the history of th | | 出版日期 | Book 2016 | | 关键词 | CMB Bispectrum; CMB Inflation; CMB Intrinsic Bispectrum; CMB Non-Gaussianity; CMB Planck; Cosmic Microwav | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-21882-3 | | isbn_softcover | 978-3-319-37295-2 | | isbn_ebook | 978-3-319-21882-3Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2016 |
