Founded in 1993 by Jean Tran Thanh Van, the association Rencontres du Vietnam, a non-profit organization and an official partner of UNESCO, has as its objective the promotion of international exchanges between Vietnam and the international community, particularly in the areas of science and education. It also aims at the encouragement and integration of Vietnamese scientists into the international scientific community and at supporting the role of education and science by encouraging scientific awareness and stimulating passion for science in the younger generation. The Rencontres du Vietnam lies within the scope of two series of scientific meetings created by Jean Tran Thanh Van : the Rencontres de Moriond in 1966 and the Rencontres de Blois in 1989.

The creation of the International Centre for Interdisciplinary Science Education (ICISE) in the city of Quy Nhon (Central Vietnam) has the ambitious objective to focus on developing Science and Education by fostering exchanges between Asia-Pacific scientists and colleagues from other parts of the world.

XVIth Rencontres du Vietnam
“The Golden Universe : Nuclear Astrophysics & Cosmic Rays
in the Multimessenger Era”

August 16 – 22, 2020 , Quy Nhon, Vietnam

Scientific Rationale

2017 marked the beginning of multi-messenger astrophysics: gravitational waves detectors found a neutron star merger for the first time, and its electromagnetic counterpart revealed spectroscopic evidence that neutron star mergers are nucleosynthesis sites of the rapid neutron-capture process (r-process), which could be responsible of the formation of some heavy elements such as gold. The implication of nuclear data and nuclear physics models is of prime importance to understand astrophysical nucleosynthesis, but also the structure and interior of neutron stars.

Cosmic-rays, that can reach us from distant supernovae, are also material messengers of nuclear processes in the Universe. Highest energy sources are unknown, and the first significant cosmic ray anisotropy, also reported in 2017, is a clue to their origin. Cosmic-rays interactions with the Earth’s atmosphere produce air showers, which provide a test bed for theories of hadronic interactions. The fact that the Pierre Auger Observatory has detected more muons from cosmic-ray showers than predicted by the most up-to-date hadronic interaction models, is a puzzle. The implication of nuclear data and hadronic interaction models is of prime importance for cosmic ray astrophysics.

Therefore, we decided to open a new series of conferences, entitled “Nuclear Astrophysics & Cosmic Rays in the Multimessenger Era” . The aim of these interdisciplinary conferences is to bring together experts involved in Nuclear Astrophysics and Cosmic Rays, to provide ample exchange of the new results and recent progress in these distinct but closely related research areas and provide the new generation with a broad perspective of the field.
