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…
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…
Growth of Massive Black-Holes in FFB Galaxies at Cosmic Dawn
Avishai Dekel, Nicholas C. Stone, Dhruba Dutta Chowdhury +4
The scenario of feedback-free starbursts (FFB), which predicts excessively bright galaxies at cosmic dawn as observed using JWST, may provide a natural setting for black hole (BH)…
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…
