A 3D view on the local gravitational instability of cold gas discs in star-forming galaxies at $0\lesssim \mathrm{z}\lesssim 5$

C. Bacchini, C. Nipoti, G. Iorio +6

Local gravitational instability (LGI) is considered crucial for regulating star formation and gas turbulence in galaxy discs, especially at high redshift. Instability criteria usua…
