Project C1

Project leaders: Weiß, Axel (MPIfR); Riechers, Dominik (PH1)

Project C1 will study the physical conditions, chemical evolution, ISM enrichment and feedback processes at high redshift over a large range in galaxy properties including typical galaxies, AGN hosts, extreme starbursts, strongly-lensed systems, and clustered vs. field environments from z≈1 up to z≈7–9. We will do so by combining exciting and future multi-wavelength observations from the most competitive new facilities including JWST, ALMA, NOEMA, VLA, and MeerKAT. The aim is to obtain spatially resolved information at scales comparable to those in local galaxies of the baryon cycle by investigating gas outflow/infall, the enrichment of the ISM and the conditions of high mass star formation through cosmic time. Our first successful investigations and proof-of-concept studies demonstrates the vastly different physical conditions in massive, high redshift galaxies compared to the local universe. This shows that our understanding of high mass star formation trough cosmic time remains incomplete when only the local universe is considered.
