Radioactive nuclei play a significant role in many current astrophysical quests. From the origin of the elements through the driving of the emissions from supernovae (56Ni) and kilonovae (r-process radioactivity), they are crucial for direct studies of galactic enrichment (7Be, 26Al, 44Ti, 60Fe, 99Tc, 244Pu, ...) and for new insights on stellar explosions (56/57Ni, 44Ti).

We would like to invite you to participate in a JINA-CEE sponsored workshop on all things R-matrix that will be held from June 21 - 25, 2021 at Ohio University in Athens, OH, USA.

Nuclei in the Cosmos is the most important international meeting in the field of nuclear astrophysics. It brings together nuclear experimentalists, nuclear theorists, astronomers, theoretical astrophysicists, cosmo-chemists, and others interested in the scientific questions at the interface of nuclear physics and astrophysics. These questions concern, for example, the origin of the elements in the cosmos and the nuclear reactions that occur in the big bang, in stars, and in stellar explosions.
