Michael D. Stage (Section 01)
This course applies physics to understand the astronomical phenomena related to galaxies. The structure and evolution of galaxies will be examined, exploring both the interrelationship of stars, gas, and dust in galaxies and the interaction of galaxies in groups or clusters. Concepts of stellar populations and the feedback between stars and galaxies through star formation and death will be used to understand the differences between elliptical, spiral, and irregular galaxies and their structure as seen using radio, optical, and high-energy telescopes. Galactic rotation and other motions will be studied to reveal evidence of dark matter as a significant constituent of the known universe, and to understand the source of spiral arms and bars in some galaxies. Evidence for massive black holes at the centers of galaxies will be discussed.
Requisite: ASTR 228 or ASTR 335, PHYS 117/124 or equivalent. Recommended requisite: PHYS 225. Spring semester. Visiting Professor Stage.
