Abstract:
Understanding how distant galaxies enriched their ISM with metals and dust is key to understanding early galaxy evolution. In this talk, I will discuss early metal and dust enrichment in the context of the REBELS-IFU program, which combines JWST and ALMA observations of 12 massive galaxies at z ~ 7. Using JWST/NIRSpec spectroscopy, I will show that these galaxies appear more metal-enriched than the typical galaxy population at this early epoch. I will then combine the metallicity measurements with ALMA observations of cold dust and gas to investigate the pathways of dust build-up in the early Universe.
