What have we learned from JWST's discoveries at Cosmic Dawn?

30 Oct 2025, 11:30, Aula Jappelli

It is now more than three years since the first data from the James Webb Space Telescope were released. Webb's unprecedented IR sensitivity has revealed multiple surprises about the first billion years of cosmic evolution. Early galaxies and black holes were much more numerous than we imagined, and their properties are quite different from their familiar local counterparts. I will give an overview of Webb's most intriguing discoveries at cosmic dawn to date, and will discuss how these observations have modified our theoretical understanding of how galaxies and black holes form and evolve from the earliest times.

BIO: Rachel Somerville is a Senior Research Scientist at the Center for Computational Astrophysics. She previously held faculty level positions at Rutgers University, the Space Telescope Science Institute and Johns Hopkins University, and the Max Planck Institute for Astronomy. Somerville works on modeling of galaxy formation in a cosmological context and the connection between galaxies and their supermassive black holes, using a variety of techniques including analytic theory, empirical models, semi-analytic models, and numerical simulations. She has been involved with panchromatic deep surveys with Hubble, Spitzer, ALMA, JWST, and other facilities, including the HUDF, GOODS, CANDELS, CEERS, ASPECS, CONDOR and HIDING, and is on the science team of the PRIMA far-IR probe mission.
