"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. I will also review how some astronomers will use the James Webb Space Telescope to answer these questions.


We strongly encourage you to attend the colloquium in person. If that is
