Abstract

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 model 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.
