While exploring the early universe, the James Webb Space Telescope discovered a type of “little red dot” galaxy. They were densely structured and reddish in color. They existed in large numbers in the early universe, but almost completely disappeared after the age of the universe was about 2 billion years, making it one of the major problems in the astronomical community. Associate Professor Zhang Huanian and Professor Wu Qingwen's team from the School of Physics of Huazhong University of Science and Technology collaborated with Peking University and the Institute of High Energy Physics of the Chinese Academy of Sciences to conduct research based on nearly 100 spectrally confirmed “little red dot” samples. For the first time, the mystery of its disappearance was revealed from the perspective of large-scale environmental and dark matter halo mass evolution. The relevant research results were published online in the international academic journal “Nature - Astronomy” on October 8.
