Description
Galaxy formation and evolution are shaped by the interplay of multiple astrophysical processes, including star formation, stellar feedback, and the cooling and retention of gas within a galaxy’s gravitational potential. These processes imprint distinct signatures on the chemical enrichment history of galaxies, making stellar metallicity a particularly sensitive tracer of their combined influence. In this talk, I will present our recent work that leverages stellar metallicity to probe the galaxy–halo connection and disentangle the relative roles of star formation, feedback, and potential-regulated gas retention in shaping galaxy properties, using both cosmological hydrodynamical simulations and semi-analytical models.
