Dark Radiation Emerging After Big Bang Nucleosynthesis?
Dark Radiation Emerging Big Bang Nucleosynthesis
2010/12/27
We show how recent data from observations of the cosmic microwave background may suggest the presence of additional radiation density which appeared after big bang nucleosynthesis. We propose a gener...
High-energy break-up of 6Li as a tool to study the Big-Bang nucleosynthesis reaction 2H(alpha,gamma)6Li
High-energy break-up 6Li tool study the Big-Bang nucleosynthesis reaction 2H(alpha,gamma)6Li

The recently claimed observations of non-negligible amounts of 6Li in old halo stars have renewed interest in the Big-Bang Nucleosynthesis (BBN) of 6Li. One important ingredient in the predicted BBN a...
Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity
Concentric circles WMAP data provide evidence violent pre-Big-Bang activity

Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang B, whose conformal infinity I is identified, conformally, with B, now regarded as a spacelike 3-surface.
