银河系与近邻星系结构与星族研讨会在云南丽江召开
The Symposium on the Structure and Stellar Populations of the Milky Way and Nearby Galaxies was held in Lijiang, Yunnan Province
银河系与近邻星系是揭示星系形成与演化规律的关键研究对象。银河系内可对海量单星进行精细观测，而近邻星系则提供了覆盖多种环境的大样本数据，二者形成高度互补。当前，随着恒星与星系巡天数据的迅速积累，银河系与近邻星系研究正迎来前所未有的发展契机。
为进一步促进两个领域的深度交叉与融合，充分发挥观测互补优势，深化对星系结构与演化的理解，2026年8月2日至5日，由云南大学中国西南天文研究所主办、北京师范大学协办、依托国家重点研发计划“基于梦飞巡天望远镜和高能天文卫星的近邻宇宙与时域天文前沿研究”项目资助的“银河系与近邻星系结构与星族研讨会”在云南省丽江市召开。来自中国科学院国家天文台、中国科学技术大学、北京师范大学、厦门大学、上海交通大学、中山大学、广州大学、南京大学、内蒙古大学、云南大学等高校和研究机构的40余位专家学者与研究生参加了此次会议。
本次会议聚焦银河系与近邻星系的多波段观测、结构与动力学、星族性质等前沿研究方向。会议期间，与会专家学者围绕上述议题作了精彩的学术报告，并展开了深入而热烈的交流讨论。同时，会议专题讨论了梦飞巡天望远镜在上述领域中的潜在贡献，与会代表就其巡天规划、科学目标与数据应用等议题积极建言献策。
会议的成功召开推动了梦飞巡天望远镜高精度真彩色巡天的更好实施，促进了银河系与近邻星系结构与星族研究领域的协同合作，有效加强了国内相关领域学者间的合作交流，为充分发挥梦飞巡天望远镜的科学潜力、提升我国在星系形成与演化研究领域的国际影响力奠定了良好基础。
The Milky Way and nearby galaxies are key research subjects for revealing the laws of galaxy formation and evolution. Within the Milky Way, precise observations can be made of massive numbers of individual stars, while nearby galaxies provide large-sample data covering a wide range of environments; the two are highly complementary. At present, with the rapid accumulation of stellar and galactic survey data, research on the Milky Way and nearby galaxies is ushering in unprecedented development opportunities.
To further promote in-depth cross-disciplinary exchange and integration between the two fields, give full play to the complementary advantages of observations, and deepen the understanding of galaxy structure and evolution, the "Symposium on the Structure and Stellar Populations of the Milky Way and Nearby Galaxies" was held in Lijiang City, Yunnan Province, from August 2 to 5, 2026. The symposium was hosted by the South-Western Institute for Astronomy Research (SWIFAR) of Yunnan University, co-organized by Beijing Normal University, and supported by the National Key R&D Program project "Frontier Research on the Nearby Universe and Time-Domain Astronomy Based on the Mephisto Sky Survey Telescope and High-Energy Astronomy Satellites." Participants registered on August 2, academic presentations and discussions were held on August 3 and 4, and the symposium concluded on August 5. More than 40 experts, scholars, and graduate students from universities and research institutions—including the National Astronomical Observatories of the Chinese Academy of Sciences, the University of Science and Technology of China, Beijing Normal University, Xiamen University, Shanghai Jiao Tong University, Sun Yat-sen University, Guangzhou University, Nanjing University, Inner Mongolia University, and Yunnan University—participated in the symposium.
The symposium focused on frontier research directions such as multi-wavelength observations, structure and dynamics, and stellar population properties of the Milky Way and nearby galaxies. During the symposium, participating experts and scholars delivered excellent academic reports and engaged in in-depth and lively discussions. In addition, the symposium held special discussions on the potential contributions of the Mephisto Sky Survey Telescope in the above fields, and the participants offered active suggestions on its survey planning, scientific goals, and data applications.
The successful convening of the symposium advanced the better implementation of the Mephisto Sky Survey Telescope's high-precision true-color survey, promoted collaborative cooperation in research on the structure and stellar populations of the Milky Way and nearby galaxies, and effectively strengthened cooperation and exchange among domestic scholars in related fields, laying a solid foundation for giving full play to the scientific potential of the Mephisto Sky Survey Telescope and enhancing China's international influence in galaxy formation and evolution research.
