Giant Clumps in Simulated High-z Galaxies: Properties, Evolution and Dependence on Feedback
Nir Mandelker, Avishai Dekel, Daniel Ceverino +3
We study the evolution of giant clumps in high-z disc galaxies using AMR cosmological simulations at redshifts z=6-1. Our sample consists of 34 galaxies, of halo masses 10^{11}-10^…
Evolution of Galaxy Shapes from Prolate to Oblate through Compaction Events
Matteo Tomassetti, Avishai Dekel, Nir Mandelker +6
We study the evolution of global shapes of galaxies using cosmological simulations. The shapes refer to the components of dark matter (DM), stars and gas at the stellar half-mass r…
Non-linear violent disc instability with high Toomre's Q in high-redshift clumpy disc galaxies
Shigeki Inoue, Avishai Dekel, Nir Mandelker +3
We utilize zoom-in cosmological simulations to study the nature of violent disc instability (VDI) in clumpy galaxies at high redshift, --. Our simulated galaxies are not in…
The Confinement of Star-Forming Galaxies into a Main Sequence through Episodes of Gas Compaction, Depletion, and Replenishment
Sandro Tacchella, Avishai Dekel, C. Marcella Carollo +5
Using cosmological simulations, we address the properties of high-redshift star-forming galaxies (SFGs) across their main sequence (MS) in the plane of star-formation rate (SFR) ve…
Evolution of Density Profiles in High-z Galaxies: Compaction and Quenching Inside-Out
Sandro Tacchella, Avishai Dekel, C. Marcella Carollo +5
Using cosmological simulations, we address the interplay between structure and star formation in high-redshift galaxies via the evolution of surface density profiles. Our sample co…
