Series: Astronomy Colloquium
Date: Wednesday 23-Oct-2024
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Jed McKinney (University of Texas)
Title: Into the Dark: The Role of Dust in Shaping Galaxy Evolution
Astrophysical dust makes up less than 1% of the mass in galaxies but plays a transformative role in shaping their evolution. My research focuses on dust both as a lens through which to chart galaxy evolution, and also as a key ingredient in multi-scale astrophysical processes. In this talk I will highlight recent observations using JWST and ALMA to uncover dust-obscured star-formation and growing supermassive black holes across cosmic history. I will present work using large extragalactic imaging surveys with JWST and other facilities, as well as more focused spectroscopic follow-up. Both approaches are needed to first build statistical samples of the most massive and active galaxies in the Universe, and then understand what makes them tick. Finally, I will comment on future far-infrared space telescope mission concepts that will delve further into the dusty Universe than ever before.
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.
