Universal bimodality in kinematic morphology and the divergent pathways to galaxy quenching
Bitao Wang, Yingjie Peng, Michele Cappellari
The hierarchical structure formation of our Universe inherently involves violent and chaotic episodes of mass assembly such as galaxy mergers. The level of bulk rotation of the col…
The HI reservoir in central spiral galaxies and the implied star formation process
Jing Dou, Yingjie Peng, Qiusheng Gu +14
The cold interstellar medium (ISM) as the raw material for star formation is critical to understanding galaxy evolution. It is generally understood that galaxies stop making stars…
Exploring the origin of cold gas and star formation in a rare population of strongly bulge-dominated early-type Galaxies
Fujia Li, Enci Wang, Ming Zhu +7
We analyze the properties of a rare population, the strongly bulge-dominated early-type galaxies (referred to as sBDEs) with significant HI gas, using the databases from the FAST A…
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…
Disk Assembly of the Milky Way Suggested from the Time-resolved Chemical Abundance
Enci Wang, Jianhui Lian, Yingjie Peng +1
Both simulations and observations suggest that the disk assembly of galaxies is governed by the interplay between coplanar gas inflow, ex-planar gas outflow and in-situ star format…
The Physical Origin of the Mass-Size Relation and Its Scatter of Disk Galaxies
Min Du, Hong-Chuan Ma, Wen-Yu Zhong +3
Utilizing a kinematic decomposition of simulated galaxies, we focus on galaxies with tiny kinematically inferred stellar halos, indicative of weak external influences. We investiga…
