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 th... Lees meer.

The present-day universe formed out of an initially hot dense rapidly expanding plasma which cooled during the expansion to become a neutral gas. Under the influence of gravity small initial fluctuations in the density grew over time until the first sources of light... Lees meer.
