Observational Evidence for Anisotropic Metal Excess around Galaxies
Cheqiu Lyu, Enci Wang, Zeyu Chen +4
The exchange of matter and energy between galaxies and their surroundings drives the cosmic baryon cycle, yet mapping metal transport remains an observational challenge. While simu…
A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Stellar metallicity gradients () provide a fossil record of the assembly history of galaxies. We present an analysis of for 90 nearby low-mass galaxies u…
AVID: A Near-Major Post-Merger of Late-Type Dwarfs beneath a Regularly Rotating HI Disk (VCC 693)
Fujia Li, Hong-Xin Zhang, Elias Brinks +23
On the periphery of galaxy clusters, moderately high galaxy densities and velocity dispersions favour interactions and mergers that influence galaxy evolution prior to cluster infa…
The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
Bojun Tao, Hong-Xin Zhang, Wenting Wang +8
Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information about galaxy merger hi…
Updated Metallicity Diagnostics for Precision Oxygen Abundance Measurements in High-redshift Galaxies with JWST
Shihong Liu, Yu Rong, Tie Li +7
Recent work has demonstrated that widely used strong-line oxygen abundance indicators, such as O3N2, , and , suffer from large uncertainties when applied…
First Statistical Detection of MgII-traced Cool Gas Outflows with JWST Towards Cosmic Dawn
Cheqiu Lyu, Haoran Yu, Enci Wang +9
Galactic-scale outflows are a crucial component of galaxy evolution, yet their properties in the early universe remain poorly constrained. We present the first statistical investig…
Stellar feedback drives the baryon deficiency in low-mass galaxies
Haoran Yu, Enci Wang, Zeyu Chen +8
Stellar feedback, as a key process regulating the baryon cycle, is thought to greatly redistribute baryonic material inside and outside the dark matter halos (DMHs), however the ob…
Transition from Outside-in to Inside-Out at : Evidence from Radial Profiles of Specific Star Formation Rate based on JWST/HST
Jie Song, Enci Wang, Cheng Jia +7
By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi-wavelength morphologies of galaxies in the…
Central Concentration and Escape of Ionizing Photons in Galaxies at the Epoch of Reionization
Cheqiu Lyu, Enci Wang, Junxian Wang +9
Compact, low-mass galaxies with strong nebular emission are considered promising candidates for efficient ionizing photon production and escape. We present a spatially resolved ana…
The Cosmic Evolution and Spatial Distribution of Multiphase Gas associated with QSOs
Zeyu Chen, Enci Wang, Hu Zou +10
We investigate the multi-phase gas surrounding QSOs traced by 33 absorption lines (e.g., Ly, C\,\textsc{iv}, Fe\,\textsc{ii}, Mg\,\textsc{ii}, etc.) in the stacked spectra of ba…
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…
Symmetry in Fundamental Parameters of Galaxies on the Star-forming Main Sequence
Zhicheng He, Enci Wang, Luis C. Ho +4
The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stella…
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…
Potential-Driven Metal Cycling: JADES Census of Gas-Phase Metallicity for galaxies at 1 < z < 7
Cheng Jia, Enci Wang, Cheqiu Lyu +9
The gravitational potential is established as a critical determinant of gas-phase metallicity (12+log(O/H)) in low-redshift galaxies, whereas its influence remains unconfirmed at h…
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…
Galaxy mass dependence of metal-enrichment of nuclear star clusters
Wenhe Lyu, Hong-Xin Zhang, Sanjaya Paudel +5
Nuclear Star Clusters (NSCs) are commonly found in galaxy centers, but their dominant formation mechanisms remain elusive. We perform a consistent analysis of stellar populations o…
Bipolar blobs as evidence of hidden AGN activities in the low-mass galaxies
Yao Yao, Enci Wang, Zhicheng He +4
We report the evidence of a hidden black hole (BH) in a low-mass galaxy, MaNGA 9885-9102, and provide a new method to identify active BH in low mass galaxies. This galaxy is origin…
