Astronomy 452H - Astrophysics II:Galaxies

The application of physics to the understanding of astronomical phenomena. Physical processes in the gaseous interstellar medium: photoionization in HII regions and planetary nebulae; shocks in supernova remnants and stellar jets; energy balance in molecular clouds. Dynamics of stellar systems: star clusters and the virial theorem; galaxy rotation and the presence of dark matter in the universe; spiral density waves. Quasars and active galactic nuclei: synchroton radiation; accretion disks; supermassive black holes. Physical processes in the gaseous interstellar medium: photoionization and HII regions and emission lines; shocks in supernova remnants and stellar jets; energy balance in molecular clouds. Quasars and active galactic nuclei: synchroton radiation; accretion disks; supermassive black holes. Students are involved in the course in discussions, oral presentations, and lab projects. The course is being taught at a higher level than a non-honors course, and a strong background in physics and math is required.

Open to Senior and Junior Astronomy majors and minors only. Pre Req: 4 PHYSICS courses
