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…
The Dekel-Zhao profile: A mass-dependent dark-matter density profile with flexible inner slope and analytic potential, velocity dispersion, and lensing properties
Jonathan Freundlich, Fangzhou Jiang, Avishai Dekel +6
We explore a function with two shape parameters for the dark-matter halo density profile subject to baryonic effects, which is a special case of the general Zhao family of models a…
