The THESAN-ZOOM project: clumpiness of high-redshift galaxies and its connection to bursty star formation
Zihao Wang, Xuejian Shen, Rahul Kannan +12
Recent JWST observations have revealed diverse high-redshift galaxy morphologies, including a population with irregular and clumpy structures. The physical origin of these structur…
Probing the molecular gas content of galaxies in an over-dense group at z~0.7: a test case for environmental quenching
Jonathan Freundlich, Benoît Epinat, Thierry Contini +14
To probe the impact of group environment on molecular gas reservoirs at intermediate redshift, we observed the CO(2-1) emission in the galaxy group COSMOS-Gr30 at with…
Controlled Experiments on Dark-Matter Halo Structure and Galaxy Morphology I: What Sets Galaxy Sizes?
Guangze Sun, Fangzhou Jiang, Jing Wang
The properties of galaxies are intricately linked to the characteristics of their host dark-matter haloes. We use a suite of controlled simulations of isolated galaxies to quantify…
Galaxy Metallicity Gradients in the Reionization Epoch from the FIRE-2 Simulations
Xunda Sun, Xin Wang, Fangzhou Jiang +10
We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the…
Halo assembly bias in the early Universe: a clustering probe of the origin of the Little Red Dots
Zihao Wang, Fangzhou Jiang, Haonan Zheng +5
The clustering of galaxies encodes key information about the structure and assembly history of their host dark matter (DM) haloes, providing a powerful probe of the origin of extre…
Ultra-diffuse galaxies in the EAGLE simulation
Haonan Zheng, Shihong Liao, Liang Gao +1
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their propert…
