Cold Stream Penetration of Virial Shocks: Fragmentation, Coagulation, and Disruption in the Hot Circumgalactic Medium
Zhiyuan Yao, Nir Mandelker, S. Peng Oh
The paper uses 3D hydrodynamic simulations to study how cold gas streams interact with the hot circumgalactic medium of massive halos, identifying regimes of coagulation, fragmenta…
Feedback-Free Star Formation in Clusters within a Galaxy Simulated at High Resolution in Cosmic Dawn
Hou-Zun Chen, Zhaozhou Li, Avishai Dekel +3
We perform a cosmological zoom-in simulation of a massive galaxy ( at ) using the GIZMO code. By employing resolution and a $3.4\…
Impact of Cosmic Filaments on Galaxy Morphological Evolution and Predictions of Early Cosmic Web Structure for Roman
Farhanul Hasan, Haowen Zhang, Viraj Pandya +10
We leverage the IllustrisTNG cosmological simulations to test how the large-scale cosmic web shapes galaxy morphology and to forecast the early cosmic web structure that the Nancy…
Statistical Properties of Cold Streams In Massive Star-Forming Halos in TNG50
Isabel Medlock, Daisuke Nagai, Nir Mandelker +4
Cold, dense streams of gas are predicted to penetrate deeply into massive halos (> 10^12 Msun) at cosmic noon (z=4-2), fueling galaxies to sustain high star formation rates. We inv…
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…
