报告摘要:
Recent observations report a puzzling dearth of dark matter (DM) in a fraction of massive high-z galaxies and dwarf galaxies, challenging current simulation predictions within the standard ΛCDM scenario. This discrepancy underscores our limited understanding of the halo/galaxy structural evolution. Here, I will present a novel unified analytical framework for galaxy dynamical evolution driven by feedback outflows, mergers, and tidal interaction, and show how these processes can augment structural diversity and form DM-deficient galaxies.

Zhaozhou Li (李昭洲, https://syrte.github.io/) is an associate professor at Nanjing University. Before joining Nanjing, he was a postdoc at The Hebrew University of Jerusalem in Israel (2021–2025) partly supported by a Marie Skłodowska-Curie Fellowship (2023–2025), and earlier at Shanghai Jiao Tong University in China (2018–2021). He received his PhD from the Shanghai Astronomical Observatory in China (2011–2017). His main research interests include galaxy formation and dynamics, dark matter halos, early galaxies, and the Local Group.
