Resolving conclusions about the early Universe requires accurate nuclear measurements

Cyril Pitrou, Alain Coc, Jean-Philippe Uzan +1

Nuclear physics experiments give reaction rates that, via modelling and comparison with primordial abundances, constrain cosmological parameters. The error bars of a key reaction,…

A new tension in the cosmological model from primordial deuterium?

Cyril Pitrou, Alain Coc, Jean-Philippe Uzan +1

Recent measurements of the D(p,He, nuclear reaction cross-section and of the neutron lifetime, along with the reevaluation of the cosmological baryon abundance from cosmic mi…

The impact of turbulent mixing on the galactic r-process enrichment by binary neutron star mergers

Irina Dvorkin, Frédéric Daigne, Stéphane Goriely +2

We study the enrichment of the interstellar medium with rapid neutron capture (r-process) elements produced in binary neutron star (BNS) mergers. We use a semi-analytic model to de…

Precision Big Bang Nucleosynthesis with the New Code PRIMAT

Cyril Pitrou, Alain Coc, Jean-Philippe Uzan +1

Precision on primordial abundances, deduced from observations, have now reached the percent level for 4He and deuterium. Precision on big bang nucleosynthesis (BBN) predictions sho…

Constraining -Process Production of Fluorine through Cosmic Ray Nucleosynthesis

Keith A. Olive, Elisabeth Vangioni

Fluorine is massive enough that it is not considered to be a light () element, yet compared to its near neighbors, C, N, O, and Ne, it is far underproduced in the course of…

The Cosmic Evolution of Magnesium Isotopes

E. Vangioni, K. A. Olive

The abundance of magnesium in the interstellar medium is a powerful probe of star formation processes over cosmological timescales. Magnesium has three stable isotopes, 24Mg, 25Mg,…
