On the origin of compressive turbulence in protoclumps in high redshift disks
Omry Ginzburg, Avishai Dekel, Nir Mandelker +4
The giant, star forming clumps in gas-rich, high redshift disks are commonly assumed to form due to gravitational instabilities, in which protoclumps have a Toomre- parameter le…

Formation of Giant Clumps in High- Disc Galaxies by Compressive Turbulence
Nir Mandelker, Omry Ginzburg, Avishai Dekel +4
We address the formation of giant clumps in violently unstable gas-rich disc galaxies at cosmic noon. While these are commonly thought to originate from gravitational Toomre instab…
