This is a bi-lingual blog of the members of the ADAMIS team at Laboratoire APC and invited guests. We comment on selected papers and events exploring, or relevant to, the interface between physics, cosmology, applied math, statistics, and numerical algorithms and which we have found interesting.

The opinions expressed in this blog reflect those of their authors and neither that of the ADAMIS group as a whole nor of Laboratoire APC.

New evidence for sterile neutrinos ... [arXiv1101.2755]

It looks like new evidence is slowly mounting in favor of some extra, 'sterile' families of neutrinos, coming from some hitherto uninvolved in the issue corners, and supporting some earlier results, which were also commented on in this blog.

Une nouvelle physique accessible grâce à la nucléosynthèse ? [1011.1054]


La nucléosynthèse (BBN pour Big Bang Nucleosynthesis) correspond à l'époque de création des éléments légers dans notre Univers en expansion. L'observation précise des quantités respectives d'hydrogène, de deutérium, de l'hélium, de berilium et de lithium permet de contraindre et de sonder différents scénarios d'évolution de l'Univers : c'est le sujet de cette revue écrite par deux chercheurs du Perimeter institute for Theoretical Physics.
