Tommaso Treu (UCLA): "The Formation of Galaxies And Supermassive Black Holes. Early Results from JWST"

In just six months, JWST has revolutionized our understanding of the universe. Its unprecedented sensitivity and angular resolution have given us a new view of the cosmos, enabling new discoveries in many areas of astronomy. I will describe first results from my GLASS-JWST Early Release Science Program and a GO program entitled "A Complete Census of Supermassive Black Holes and Host Galaxies at z=6", aimed at understanding how the first galaxies and black holes form, grow, and cause the last major phase transition of the universe, called "cosmic reionization." Highlights include: i) the discovery of an hitherto unknown population of luminous galaxies at z>10, indicating that galaxies formed earlier and faster than previously thought; ii) the characterization of the relationship between black holes and their host galaxies at z=6.
