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}…
Disk Assembly of the Milky Way Suggested from the Time-resolved Chemical Abundance
Enci Wang, Jianhui Lian, Yingjie Peng +1
Both simulations and observations suggest that the disk assembly of galaxies is governed by the interplay between coplanar gas inflow, ex-planar gas outflow and in-situ star format…
