An emerging baryon cycle in a galaxy 500 million years after the Big Bang
Shengzhe Wang, Xin Wang, Hang Zhou +17
The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…
Satellite quenching by radio jets of central galaxies in galaxy groups
Yijun Wang, Tao Wang, Dingyi Zhao +9
Feedback from active galactic nuclei (AGN) is now recognized as a key component of galaxy formation models. It plays a central role in regulating the growth and quenching of galaxi…
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\…
A Bending in the Size-mass Relation of Star-forming Galaxies across at a Critical Stellar Mass of Revealed by JWST
Longyue Chen, Tao Wang, Hanwen Sun +12
We investigate the rest-frame optical size-stellar mass relation of galaxies at using deep JWST/NIRCam and MIRI imaging from the PRIMER survey. We find that star-formin…
The Broken Similarity: Sinking and Merging of Dark Matter Subhalos Across Hierarchical Levels
Wenkang Jiang, Jiaxin Han, Kun Xu +6
We investigate hierarchical mergers among subhalos within a CDM simulation using the HBT+ subhalo finder. Unlike previous methods, HBT+ tracks subhalo evolution across hierarch…
The tidal evolution of satellite galaxies in cosmological simulations: insights from COLIBRE
Feihong He, Jiaxin Han, Joop Schaye +14
We investigate the co-evolution of the stellar and dark matter mass of satellite galaxies using the COLIBRE cosmological hydrodynamical simulations with subhaloes resolved by the h…
