From FFB Starbursts at Cosmic Dawn to Quenching at Cosmic Morning: Hi-z Galaxy Bimodality

Avishai Dekel, Nir Mandelker, Zhaozhou Li +5

We propose a mass-dependent bimodality in the early evolution of galaxies. The massive track connects the super-bright galaxies at cosmic dawn () to the super-massive quiesc…

Radial Transport in High-Redshift Disk Galaxies Dominated by Inflowing Streams

Dhruba Dutta Chowdhury, Avishai Dekel, Nir Mandelker +2

We study the radial transport of cold gas within simulated disk galaxies at cosmic noon, aiming at distinguishing between disk instability and accretion along cold streams from the…

The nature of giant clumps in high-z discs: a deep-learning comparison of simulations and observations

Omri Ginzburg, Marc Huertas-Company, Avishai Dekel +4

We use deep learning to explore the nature of observed giant clumps in high-redshift disc galaxies, based on their identification and classification in cosmological simulations. Si…

Stellar Masses of Giant Clumps in CANDELS and Simulated Galaxies Using Machine Learning

M. Huertas-Company, Y. Guo, O. Ginzburg +12

A significant fraction of high redshift star-forming disc galaxies are known to host giant clumps, whose nature and role in galaxy evolution are yet to be understood. In this work…

Origin of Star-Forming Rings around Massive Centres in Massive Galaxies at

Avishai Dekel, Sharon Lapiner, Omri Ginzburg +9

Using analytic modeling and simulations, we address the origin of an abundance of star-forming, clumpy, extended gas rings about massive central bodies in massive galaxies at $z \!…

A mass threshold for galactic gas discs by spin flips

Avishai Dekel, Omri Ginzburg, Fangzhou Jiang +4

We predict, analytically and by simulations, that gas discs tend to survive only in haloes above a threshold mass (stellar mass )…
