July 24-30, 2022, ICISE, Quy Nhon, Vietnam
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.
ExploraScience and the Development of Astronomy and Education in Vietnam
The ICISE center is associated with the first, and so far, unique, science park in Vietnam, called “ExploraScience”. Under construction for several years, with some delays due to the Covid-19 pandemic but with the never-failing support of the local authorities of the Binh Dinh Province, ExploraScience is finally emerging. The Planetarium has started public operations a few weeks ago, and the Observatory, a “satellite” of the Planetarium, is now completed. A 60-cm telescope has been installed, and the dome, manufactured in Vietnam, is in a test phase. Hopefully the Observatory will be operational in time for the Conference. A visit will be organized with the participation of representatives of two Offices of the International Astronomical Union (IAU), the Office of Astronomy Outreach (based in Tokyo, Japan) and the Office for Astronomy Education (based in Heidelberg, Germany). Also, a group of Vietnamese astrophysicists has just been formed, with the support from the Simons Foundation. The local community of ICISE and ExploraScience is eager to meet the participants and guests of the Golden Universe conference, which they see as a strong encouragement to foster astronomy and astrophysics in Vietnam, and a tool to develop scientific research in this still developing country.

XVIIIth Rencontres du Vietnam
“THE GOLDEN UNIVERSE: Nuclear Astrophysics & Cosmic Rays in the Multimessenger Era”
July 25-29, 2022, Quy Nhon, Vietnam
Scientific Rationale of the Conference
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-ray 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. Heavy nuclei and cosmic rays are also of prime importance for astrobiology.
