Vietnamese scientists have made many contributions in the field of astrophysics.

DNVN – Within the framework of the SAGI 2025 Astrophysics conference held at the ICISE Center (Binh Dinh), scientists assessed that in recent years, the field of astrophysics has had breakthrough research results, including important contributions from Vietnamese scientists.

Taking place over 5 days (May 26-30) at the International Center for Interdisciplinary Science andEducation (ICISE, Quy Nhon - Binh Dinh), the SAGI 2025 Astrophysics Conference attracted nearly 60 delegates, including scientists, researchers, and students from 10 countries and territories (attending in person and online), to discuss in depth about star formation and cosmic dust physics - two fields that are deeply related to each other.

According to Associate Professor Dr. Pham Ngoc Diep - Vietnam Space Center (VNSC), the main content of the conference is to focus on the process of gas and dust clouds in the interstellar medium collapsing to form new stars, planetary systems and the growth of super black holes.

The main topics of the workshop include: physical mechanisms causing the orientation of cosmic dust and polarized radiation; methods for measuring magnetic fields using polarized radiation and other complementary techniques.

The formation and evolution of stars, exoplanets and solar systems, the growth of supermassive black holes, and the evolution of galaxies; projects to develop new observational facilities around the world .

Among them are important presentations, such as: “New properties of Sub-Alfvenic Turbulence and applications to magnetic field measurements” presented by Prof. Dr. Alex Lazarian (University of Wisconsin-Madison, USA); “Unified theory of cosmic dust orientation” presented by Prof. Dr. Hoang Chi Thiem (Korea Space and Astronomy Science Institute - KASI); “Overview of the BALLLAD-POL project initiated and led by a group of Vietnamese astronomers” by Assoc. Prof. Dr. Pham Ngoc Diep (Vietnam Space Center)…

Prof. Dr. Hoang Chi Thiem (Korea Space and Astronomy Science Institute - KASI), presented a paper.

Sharing at the conference, Prof. Dr. Hoang Chi Thiem (KASI, Korea) assessed that in recent years, the field of astrophysics has had breakthrough research results. Typically, the phenomenon of cosmic dust orientation has been discovered everywhere in the universe, from the galaxy scale to the region forming new stars and planets, thanks to advanced telescope systems equipped with polarimeter, such as the ALMA observatory.

Magnetic fields play a key role in the formation and evolution of stars, planetary systems, and galaxies. The discovery of supermassive black holes in the early universe obscured by dust by the JWST space observatory.

“Like previous SAGI conferences, this conference provides opportunities for students and young researchers in the field of astrophysics to learn and interact with professional Vietnamese astronomers at home and abroad. At the same time, it also gives them the opportunity to meet and learn from foreign experts in this field,” said Prof. Dr. Hoang Chi Thiem.

Meanwhile, Professor Alex Lazarian from the University of Wisconsin-Madison (USA) said he was very impressed with the progress in astrophysics research in Vietnam. He was also proud that his former excellent PhD student, Professor Hoang Chi Thiem, is now one of the leading researchers contributing to the development of magnetic astronomy research in Vietnam.

“Vietnamese scientists are playing an important role in promoting the theory explaining the evolution and connection of interstellar dust in the astronomical environment. In addition, it has opened a new research direction in astronomy, which is the phenomenon of rotational destruction of dust particles when exposed to strong radiation,” said Professor Alex Lazarian.

At the same time, the professor also affirmed that this is an outstanding field that clearly demonstrates Vietnam's strengths, contributing to promoting the development of many other astronomical research directions. Through recent conferences, it has been shown that Vietnamese scientists have become pioneers in many important branches of astrophysics research.

The SAGI Astrophysics 2025 Conference is organized and sponsored by the Simons Astrophysics Group at ICISE (SAGI). Established with support from the Simons Foundation, SAGI has strived since its inception to build a pioneering research center in astrophysics in Vietnam, promoting international scientific cooperation and connecting domestic and regional scientists with the global research community. At the same time, it aims to open up new research directions and nurture the next generation of astronomers.

This year's conference is a continuation of the previous successful conference series: the SAGI Astrophysics 2022 conference on “Pioneering research directions of Astrophysics in the golden age of dust polarization” and the SAGI Astrophysics 2023 conference on dust polarization and applications in astrophysics.
