Surprising increase of electron temperature in metal-rich star-forming region
Ziming Peng, Renbin Yan, Zesen Lin +3
The electron temperature is a crucial parameter for the determination of the gas-phase metallicity of galaxies. Low electron temperature is expected for metal-rich galaxies, theore…

SDSS-IV MaNGA: Data-Model Discrepancy in Temperature-sensitive Line Ratios for Star-forming Galaxies
Ziming Peng, Renbin Yan, Xihan Ji +2
Gas-phase metallicity is a fundamental parameter that helps constrain the star-forming history and chemical evolution of a galaxy. Measuring electron temperature through auroral-to…
