Core Insights - The research team led by Professor Wang Huiyuan from the University of Science and Technology of China has discovered strong clustering of diffuse dwarf galaxies, confirming the phenomenon of "dark matter halo clustering bias" in the universe, which provides important clues for understanding the nature of dark matter and the co-evolution of cosmic large-scale structures and galaxies [1][2] Group 1: Dark Matter and Galaxy Formation - Dark matter is an invisible and non-luminous substance that shapes the structure of the universe through gravity, dominating the formation and evolution of galaxies [1] - The distribution of dark matter halos is not uniform but exhibits a "clustering" pattern, which is crucial for understanding the large-scale structure of the universe and galaxy formation [1] - The research team found that diffuse dwarf galaxies prefer to cluster together, while compact dwarf galaxies tend to be more isolated, contradicting previous findings based on massive galaxy samples [1] Group 2: Alternative Models and Theoretical Implications - The standard cold dark matter model, which is the mainstream theoretical framework for explaining the formation of large-scale structures in the universe, fails to effectively explain the new findings [2] - An alternative model considering self-interacting dark matter (SIDM) was proposed, which can explain the correlation between dark halo "age" and galaxy density, presenting unique theoretical advantages [2] - This research challenges existing galaxy formation models and provides new insights into the nature of dark matter, moving closer to unveiling its mysteries [2]
