A Universal Dance of Galactic Disks: Ubiquitous Precession and Its Implications

Enci Wang, Federico Marinacci, Hao Li, Huiyuan Wang, Mark Vogelsberger, Xiong Luo, Xuejian Shen, Yuan Wang

Galactic disks precess universally due to tidal torques from nearby matter, altering their evolution and structures over time.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that disk precession is ubiquitous in galaxies and significantly affects galaxy evolution. The precession is driven by the external tidal torque originating from the anisotropic matter distribution within 30 kpc.

C2weakest assumption

That the IllustrisTNG simulations accurately capture real gravitational interactions, tidal torques, and disk dynamics without major biases from resolution limits, subgrid physics, or numerical artifacts.

C3one line summary

Galactic disks precess ubiquitously from tidal torques, causing warps, orbital heating, and radial alignments of satellites.
