DESCRIPTION:Speakers: Francesco Belfiore (ESO Garching)\n\nChemical abunda
 nce measurements from nebular emission lines remain one of the primary too
 ls for understanding galaxy evolution across cosmic time and probing the c
 ycle of baryons in the Universe. Yet the interpretation of these diagnosti
 cs depends strongly on physical scale considered: from H II regions resolv
 ed in most nearby galaxies\, to integrated spectra from large galaxy spect
 roscopic surveys\, and increasingly distant systems observed with JWST. In
  this talk\, I will discuss recent progress toward connecting these scales
  via new modelling approaches.\nIn the local Universe these tools are help
 ing us to resolve old questions related to the discrepancy between differe
 nt abundance and density tracers. More importantly\, understanding the sma
 ll-scale physics turns out to be fundamental to interpret the deep spectra
  that JWST is providing for galaxies from Cosmic Noon to Dawn\, and their 
 puzzling abundance patterns. I will conclude by summarizing some of the ou
 tstanding challenges in drawing a coherent view of chemical abundances acr
 oss cosmic time.\n\nhttps://indico.fysik.su.se/event/9791/
