Rotational support of giant clumps in high-z disc galaxies
Rotational support of giant clumps in high-z disc galaxies
We address the internal support against total free-fall collapse of the giant clumps that form by violent gravitational instability in high-z disc galaxies. Guidance is provided by an analytic model, where the proto-clumps are cut from a rotating disc and collapse to equilibrium while preserving angular momentum. This model predicts …
