Effects of Cloud Geometry and Metallicity on Shattering and Coagulation of Cold Gas, and Implications for Cold Streams Penetrating Virial Shocks
Zhiyuan Yao, Nir Mandelker, S. Peng Oh +2
Theory and observations reveal that the circumgalactic medium (CGM) and the cosmic web at high redshifts are multiphase, with small clouds of cold gas embedded in a hot, diffuse me…

Entrainment of Hot Gas into Cold Streams: The Origin of Excessive Star-formation Rates at Cosmic Noon
Han Aung, Nir Mandelker, Avishai Dekel +3
We explore the evolution of cold streams from the cosmic web that feed galaxies through their shock-heated circumgalactic medium (CGM) at cosmic noon, . In addition to…

Feedback-Free Starbursts at Cosmic Dawn: Observable Predictions for JWST
Zhaozhou Li, Avishai Dekel, Kartick C. Sarkar +4
We extend the analysis of a physical model within the standard cosmology that robustly predicts a high star-formation efficiency (SFE) in massive galaxies at cosmic dawn due to fee…
