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…

A Vertically Orientated Dark Matter Halo Marks a Flip of the Galactic Disk
Ling Zhu, Runsheng Cai, Xi Kang +5
Unveiling the 3D shape of the Milky Way's dark-matter halo is critical to understanding its formation history. We created an innovative dynamical model with minimal assumptions on…
