The Cosmos In Its Infancy
TalkDuring Science Focus Session: Galaxies
7th Shaw-IAU Workshop
Since the launch of JWST, our view of the first stars and galaxies has come into sharp focus. Photometric and spectroscopic observations now reveal their distinct star formation histories, as well as the gas and ionization conditions that shaped galaxies in the first few hundred million years after the Big Bang. In this talk, University of Arizona Associate Research Professor and JADES team member Kevin Hainline will discuss what JWST has taught us about galaxies at z > 10 from ultra-deep observations. He will show how these galaxies are identified, how their properties have defied expectations from the Hubble era, and how our picture of the early Universe, its stars, gas, and galaxies, has evolved as a result. Finally, he’ll outline what new insights we can expect from upcoming JWST surveys in the years ahead.
About Kevin Hainline
Kevin Hainline is an astronomy professor at the University of Arizona and part of the JWST NIRCam Science Team. Within the JWST Advanced Deep Extragalactic Survey (JADES), he leads work to measure precise redshifts for the earliest galaxies in the universe. His research examines galaxy formation at cosmic dawn, the evolution of supermassive black holes, and the discovery of ultra-cool brown dwarfs in the outskirts of the Milky Way. He is also an avid science communicator, speaking at public events around the world about humanity’s relationship with the infinite.
