The MAGE Project: Size Evolution and Disk Formation in Massive Galaxies at Cosmic Dawn
Zhiyuan Yao, Avishai Dekel, Romain Teyssier +5
We investigate size evolution and disk formation with a new suite of eleven cosmological zoom-in simulations, Massive Assembly of Galaxies in the Early universe (MAGE), run with RA…

Cold Stream Penetration of Virial Shocks: Fragmentation, Coagulation, and Disruption in the Hot Circumgalactic Medium
Zhiyuan Yao, Nir Mandelker, S. Peng Oh
Cold streams penetrating virial shocks of massive halos along cosmic web filaments are expected to fuel galaxy growth at high redshift, yet the physical processes governing their p…

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\…
