NuGrid is a research collaboration focusing on nuclear astrophysics and cosmochemistry. It has developed a research platform that is based on the computing tools made available to collaborators and participants, on their know-how and on the transfer of this knowledge across the various related disciplines. The research activities are regulated according to the NuGrid manifesto.
The continuously developed and maintained tools for computation, data analysis and visualization are taking advantage of modern computing technologies. They are meant to be versatile, cross-platform and geared especially towards their use for training of undergraduate and graduate students, as well as senior scientists.
JINA was actively involved in NuGRID from its beginning, and provided critical initial support. Today, NuGrid includes more than 50 senior and young scientists from 20 different research institutes in US, Canada, Europe and Australia, many of which are active JINA-CEE members. JINA-CEE research relies heavily on NuGrid and continues to support many NuGRID projects, developments, and collaboration meetings.
Among others, fundamental research goals of the Nugrid collaboration are:
- provide sets of stellar nucleosynthesis yields including high, intermediate and low-mass stars, as well as their explosions and other nucleosynthesis sites;
- provide the relative uncertainties of these yields coming from the stellar, nuclear and numerical uncertainties/approximation;
- make the yields, the uncertainties and corresponding (stellar) models accessible to the community via web-based tools;
- provide nuclear uncertainty/sensitivity studies, aligning astrophysics needs with present and future investments of nuclear theory and experiments;
- provide uncertainty/sensitivity studies of stellar yields together with input parameters of galactic chemical evolution, in comparison with the chemical enrichment history of the Milky Way and other galaxies.
