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…

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…

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…
