The physical origin of positive metallicity radial gradients in high-redshift galaxies: insights from the FIRE-2 cosmological hydrodynamic simulations
Xunda Sun, Xin Wang, Xiangcheng Ma +11
Using the FIRE-2 cosmological zoom-in simulations, we investigate the temporal evolution of gas-phase metallicity radial gradients of Milky Way-mass progenitors in the redshift ran…
From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function
Dingyi Zhao, Yingjie Peng, Yipeng Jing +18
In CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM) t…
From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction
Zeyu Gao, Yingjie Peng, Kai Wang +18
The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional method…
Testing galaxy formation models with the stellar mass-halo mass relations for star-forming and quiescent galaxies
Kai Wang, Yingjie Peng
The tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critic…
Revisiting the fundamental metallicity relation with observation and simulation
Chengyu Ma, Kai Wang, Enci Wang +7
The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution. Beyond the fundamenta…
From Halos to Galaxies. IX. Estimate of Halo Assembly History for SDSS Galaxy Groups
Cheqiu Lyu, Yingjie Peng, Yipeng Jing +15
The properties of the galaxies are tightly connected to their host halo mass and halo assembly history. Accurate measurement of the halo assembly history in observation is challeng…
