New Insights on Stellar Mass Assembly since the Dawn of Cosmic Time

Dominik Riechers
Uni Köln

Detailed studies of distant galaxies down to sub-kiloparsec scales with powerful facilities like ALMA, combined with an overall measurement of the cold gas content of galaxies through cosmic history, have now provided strong evidence for the importance of gas flows and feedback for understanding the star and galaxy formation process. New measurements with JWST now have shown that fairly evolved galaxies already existed only a few hundred million years after the Big Bang, and that they are more numerous that previously thought. I will present some of the most intriguing new pieces of evidence for our current picture of galaxy evolution, and an outlook of the major improvements expected with the next generation of large astronomical facilities.
