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…
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…
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…
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…
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…
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…
