The reporter learned from the Chinese Academy of Sciences Shanghai Astronomical Observatory on the 25th that astronomers have recently obtained a new set of images, which reveal the complex interstellar gas filamentary structure network in the central region of the Milky Way with unprecedented precision. The series of studies was completed by the ALMA Central Molecular Region Exploration Survey project, which involved researchers from multiple countries. It includes one summary paper and multiple data analysis papers. This image was obtained by the Atacama Large Millimeter/submillimeter Wave Array (ALMA), covering an area of over 650 light-years in scale, containing a large amount of dense gas and dust clouds surrounding a supermassive black hole located at the center of the Milky Way galaxy. As one of the core members of the data processing working group, Lu Xing, a researcher at the Chinese Academy of Sciences Shanghai Astronomical Observatory, took the lead in one of the data analysis papers. Lv Xing introduced that the paper he led published two medium bandwidth spectral line window data, including images of six representative molecular spectral lines. We have discovered an abnormally strong emission of sulfur monoxide molecules within the Sgr B2 molecular cloud in the central region of the Milky Way galaxy, as well as the potential of HC15N molecules as reliable probes for dense gas molecules, and so on. ”Lv Xing said that many researchers and graduate students from the Chinese Academy of Sciences Shanghai Observatory participated in this series of studies through different working groups. Cold molecular gases are the focus of the project research. Researchers have delved into the complex chemical composition of the central region of the Milky Way galaxy, detecting dozens of different molecules ranging from simple molecules such as silicon monoxide to more complex organic molecules such as methanol, acetone, and ethanol. Project leader and professor of astrophysics at Liverpool John Moores University in the UK, Steve Longmore, stated that cold molecular gases flow along filamentous structures and converge into dense matter clusters, providing the material basis for the birth of stars. In the outer regions of the Milky Way, similar to the solar system, this process is relatively clear, but in the central region, its physical processes are more extreme. The project aims to gain a deeper understanding of how these extreme phenomena affect the process of star formation and to test whether existing theories of star formation are still applicable in extreme environments.
