Description for Probing the Early Universe with the CMB Scalar, Vector and Tensor Bispectrum
Paperback. This book shows that bispectra include unique signals that no symmetry-invariant models can produce. Computes CMB bispectra induced by scalar-mode non-Gaussianities with a preferred direction, and tensor-mode non-Gaussianities in parity-violating Weyl gravity. Series: Springer Theses. Num Pages: 193 pages, biography. BIC Classification: PGC; PHU. Category: (G) General (US: Trade). Dimension: 235 x 155 x 11. Weight in Grams: 308.
The non-Gaussianity in the primordial density fluctuations is a key feature to clarify the early Universe and it has been probed with the Cosmic Microwave Background (CMB) bispectrum. In recent years, we have treated the novel-type CMB bispectra, which originate from the vector- and tensor-mode perturbations and include the violation of the rotational or parity invariance. On the basis of our current works, this thesis provides the general formalism for the CMB bispectrum sourced by the non-Gaussianity in the scalar, vector and tensor-mode perturbations. Applying this formalism, we calculate the CMB bispectra from the two scalars and a graviton ... Read more
