The disrupted chemical enrichment history of the Milky Way driven by gas accretion

Jianhui Lian, Qinhao Shao, Min Du +4

As the only galaxy enabling temporally-resolved observations from an internal vantage point, the Milky Way as a galaxy offers unique insights into galactic chemical enrichment hist…

MAMMOTH-Grism: Gas-phase Metallicity Gradients of Star-forming Galaxies in Protocluster Environments at Cosmic Noon

Yi-Ming Yang, Xin Wang, Chao-Wei Tsai +11

Environment plays a crucial role in shaping galaxy formation, yet the impact of overdensities on the internal chemical structure of galaxies at cosmic noon is still under debate. H…

A 13-Billion-Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to with JWST and Archival Surveys

Zihao Li, Zheng Cai, Xin Wang +25

The galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and high-redshift universe, as they trace the baryon cycle an…

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…

Dominant Role of Coplanar Inflows in Driving Disk Evolution Revealed by Gas-Phase Metallicity Gradients

Cheqiu Lyu, Enci Wang, Hongxin Zhang +8

Using spatially resolved spectroscopic data from the MaNGA sample, we investigate the parameters influencing the radial gradients of gas-phase metallicity ($\nabla\log(\mathrm{O/H}…
