The dependence of Circumgalactic Medium properties on halo assembly histories in the IllustrisTNG simulations

Yiyuan Zhang, Houzun Chen, Xi Kang

While halo mass is the dominant factor shaping the embedded galaxies, the properties of the circumgalactic medium (CGM) also depend on halo assembly history. To investigate this, w…

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 ( $M_{s} \sim 1 0^{10} M_{⊙}$ at $z \sim 10$ ) using the GIZMO code. By employing $\leq 3 pc$ resolution and a $3.4\…
