Recently, a research team led by Prof. Peng Wang at the Shanghai Astronomical Observatory (SHAO), Chinese Academy of Sciences (CAS), achieved significant progress in the field of galaxy cluster angular momentum. Utilizing large-sample spectroscopic data from the Sloan Digital Sky Survey (SDSS), the team systematically revealed for the first time that galaxy clusters exhibit significant spin coherence on the celestial projection plane. This achievement, titled "The Cosmic Dance: Observational Detection of Coherent Spin in Galaxy Clusters," was published in 《The Astrophysical Journal Letters》, providing new observational clues for a deeper understanding of dynamical properties at the galaxy cluster scale.

Recently, an international team led by Shanghai Astronomical Observatory, Chinese Academy of Sciences (CAS), has developed a quantifiable, verifiable, and scalable standardized workflow for identifying Compact Symmetric Objects (CSOs), derived from milliarcsecond-level alignment between optical and radio positions by combining the high-precision astrometry of Gaia with Very Long Baseline Interferometry (VLBI) radio imaging. This achievement expands the catalog of high-quality CSO samples and provides new insights into their physical nature, jet–interstellar medium coupling, and feedback processes during the early stages of radio galaxy formation. These results were published on December 5, 2025, in the international astronomic research journal “Astronomy & Astrophysics”.

The Shanghai Astronomical Observatory PIFI Distinguished Team Project successfully held a series of international exchange activities in Shanghai from October 13 to October 25, 2025.

From October 27 to 29, 2025, the "CSST-MCI Early Science Workshop" was held at the Shanghai Astronomy Museum of the Shanghai Astronomical Observatory, CAS. The event was co-organized by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences and the CSST (China Space-Station Survey Telescope) Yangtze River Delta Regional Science Center. More than 50 representatives from various domestic research institutions and universities participated both online and in person.

A latest cosmological simulation study has systematically revealed, for the first time, how the interaction between dark matter and dark energy significantly influences the rotation and shape alignment of dark matter halos in the universe. This research provides a new perspective for understanding the formation of large-scale cosmic structures and lays an important foundation for interpreting observational data from future sky survey projects such as the China Space Station Telescope (CSST).

Recently, researchers from the Shanghai Astronomical Observatory (SHAO),the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC),Guizhou University and Yunnan Observatory, have made a collection of progress on pulsar searching, precision timing, pulsar emission properties for pulsars in Globular Clusters (GCs). These work ulitized highly sensitivity data collected with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The results have been published in a total of four papers in《ASTROPHYSICAL JOURNAL》and《Research in Astronomy and Astrophysics》

On October 17, 2025, the “SPHEREx and Earth 2.0 (ET) Space Mission Thinkshop”, hosted by the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences (CAS), was successfully held in Shanghai. The workshop was co-chaired by Professor Shrinivas R. Kulkarni, 2024 Shaw Prize Laureate in Astronomy and professor at the California Institute of Technology (Caltech), and Professor Jian Ge, Principal Investigator of the Earth 2.0 (ET) space mission at SHAO.
