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 ( at ) using the GIZMO code. By employing resolution and a $3.4\…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Weak Lensing Constraints on Dark Matter-Baryon Interactions with -Body Simulations and Machine Learning
Chi Zhang, Lei Zu, Hou-Zun Chen +2
We investigate the elastic scattering cross section between dark matter and protons using the DES Year 3 weak lensing data. This scattering induces a dark acoustic oscillation stru…
