SUMMARY:Semi-analytic Analysis of Galaxy Evolution from the Local Universe to Intermediate Redshifts: The Role of Environment\, Kinematics\, and Feedback
DESCRIPTION:Understanding galaxy evolution requires extracting physical information from integrated galaxy spectra\, including the coupled evolution of stars and gas. \nIn this talk\, I present a novel semi-analytic spectral-fitting approach that jointly and self-consistently constrains the chemical evolution of both stars and gas.The model incorporates gas inflow\, outflow\, and star formation processes\, and is fitted directly to galaxy absorption-line spectra\, while emission-line diagnostics are used to constrain the present-day gas-phase metallicity. Applying this framework to galaxies in the local Universe from SDSS-IV/MaNGA and at intermediate redshifts from COSMOS-WALL/LEGA-C\, we reconstruct their star formation and chemical enrichment histories in a self-consistent manner. Such analysis allows us to investigate how the interplay between gas accretion and outflows shapes galaxy evolution\, in particular how galaxies transition away from the star-forming main sequence and become quenched. \nWe further explore the roles of feedback from active galactic nuclei and supernovae\, as well as environmental and kinematic properties\, in regulating these processes. \nFinally\, I will discuss how forthcoming spectroscopic surveys such as WEAVE and 4MOST will provide critical data to further test and extend these scenarios. \nFecha y lugar: 13/05/2026 – 12:30 | Salón de ActosShuang ZhouINAF-OAB \n
