Series: Astronomy Colloquium
Date: Wednesday 12-Feb-2020
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. David Rupke (Rhodes College)
Title: How big are galactic winds?
Intense star formation and rapid black hole accretion in the centers of galaxies produce energy that propels gas outward. These galactic winds affect the evolution of their host galaxies, and may self-regulate the future growth of stars and black holes. Galaxies are also known to be surrounded by enormous reservoirs of gas. Galactic winds are a likely mechanism by which these reservoirs are created. However, we don't know how far most galactic winds extend into their surroundings. I will discuss observations of galactic winds driven by star formation and black holes that probe their extent and illuminate the connection between galaxies and their surroundings.
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. 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.
