Ed Buie of Vassar College will be visiting Kenyon to discuss the huge haloes of gas that provide the material from which stars are formed and what we can learn from them.

When we think of a galaxy, we often imagine a spinning disk of stars and gas surrounding a glowing center. But galaxies are more than meets the eye, and the disks we see are just a small part of the whole. We now know galaxies to be surrounded by huge halos of gas that provide the material from which stars are formed. In this lecture, we will explore the scope of these nearly invisible halos, describe how we can detect them, and look at computer simulations that help reveal their lesser-known properties and their influences, such as magnetic fields!

Join us on Friday, Feb. 23, for this exciting presentation from Ed Buie, assistant professor of astronomy at Vassar College. Lunch will be available in Hayes 216 from 11:45 a.m. to 12:15 p.m. and the presentation will begin in Hayes 211/213 at 12:10 p.m. We hope to see you there!
