Astronomy Colloquium for 2024-11-13


Series: Astronomy Colloquium
Date: Wednesday 13-Nov-2024
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Alice Shapley (UC Los Angeles)
Title: The JWST Revolution in Galaxy Formation: A Spectroscopic Perspective

Understanding the formation and evolution of galaxies remains one of the great challenges of modern cosmology. Rest-frame optical spectroscopy serves as a uniquely powerful tool for untangling many of the key processes in galaxy formation, including the nature of galaxies' stars, gas, and dust. We present a brief history of rest-optical spectroscopic probes of the galaxy formation process at high redshift, ranging from early ground-based attempts to the very latest results from the James Webb Space Telescope, which has revolutionized our ability to learn about the most distant galaxies in the universe. We focus in particular on questions related to the evolving enrichment and physical conditions in the interstellar medium of star-forming galaxies in the early universe, as these place critical constraints on the cycle of baryons through galaxies over cosmic time.


In-person colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer Dr. Richard Mushotzky. Lunch will normally be reserved for the speaker to talk to graduate students. Anyone asking a question during a talk is asked to raise their hand and be acknowledged before speaking. Contact Dr. Richard Mushotzky for details.
