The Internal Kinematics, Stellar Population, and Gas-phase Properties of The Pseudobulge in An Ultra-diffuse Galaxy: AGC721966
Shihong Liu, Yu Rong, Huiyuan Wang +8
Leveraging spectroscopic data from the Sloan Digital Sky Survey, we conduct a comprehensive analysis of the central stellar velocity dispersion, stellar population properties, star…
A negative stellar massgaseous metallicity gradient relation of dwarf galaxies modulated by stellar feedback
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Baryonic cycling is reflected in the spatial distribution of metallicity within galaxies, yet gas-phase metallicity distribution and its connection with other properties of dwarf g…
Unexpected clustering pattern in dwarf galaxies challenges formation models
Ziwen Zhang, Yangyao Chen, Yu Rong +4
The galaxy correlation function serves as a fundamental tool for studying cosmology, galaxy formation, and the nature of dark matter. It is well established that more massive, redd…
Ultra Diffuse Dwarf Galaxies Hosting Pseudo-bulges
Yu Rong, Hong-Xin Zhang, Cheng Cheng +5
By analyzing data from DESI Legacy Imaging Survey of the dwarf galaxies in the Arecibo Legacy Fast Alfa Survey, we have identified five ultra-diffuse galaxies (UDGs) featuring cent…
Intrinsic Morphology of The Stellar Components in HI-bearing Dwarf Galaxies and The Dependence on Mass
Yu Rong, Min He, Huijie Hu +2
The intrinsic morphology of stellar components within HI-bearing dwarf galaxies remains a topic of uncertainty. Leveraging the galaxy dataset derived from the cross-matched catalog…
