ABSTRACT
Recent observations reported 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 and 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. If there is time, I will also briefly introduce the feedback-free starbursts (FFBs) scenario as a potential paradigm shift for early galaxy formation.
BIO
Zhaozhou Li (李昭洲, https://syrte.github.io/) is a Marie Skłodowska-Curie fellow at The Hebrew University of Jerusalem. Before moving to Israel, he was a postdoctoral researcher at Shanghai Jiao Tong University (2018–2021) and a graduate student at Shanghai Astronomical Observatory (2011–2017). His research focuses on galactic dynamics, structure formation, the Local Group, and the formation of early galaxies. He aims to develop a theoretical understanding of cosmic structures, especially their dynamics, with the help of observations and simulations.
