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\…

From Feedback-Free Star Clusters to Little Red Dots via Compaction

Avishai Dekel, Dhruba Dutta Chowdhury, Sharon Lapiner +6

We address the origin of the Little Red Dots (LRDs) seen by JWST at cosmic morning () as compact stellar systems with over-massive black holes (BHs). We propose…

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…

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…
