Tuesday, April 29      FINAL EXAM 8-10PM                      Chapters 1-23 

Your course grade to date, including ALL three midterm exams, homeworks, quizzes, and in-class activities will be posted outside Rooms 310 and 316 no later than 5pm Friday 25 April. All papers will also be available at that time in the usual rack outside the lecture hall, PA 118.

The final exam will cover material from the entire course, including a star map. The material will be evenly split from the 3 Units.

You need not take the final exam if you are satisfied with your grade after the three midterms, quizzes, homework assignments and in-class activities. If you do take the final exam, the lowest exam score of the three midterms and the final will automatically be dropped and only the highest three exam scores will count toward your grade.

1. Sketch the Milky Way galaxy, including the halo, disk and nucleus. Label the location of the Sun, gas, dust, globular clusters, open clusters, young and old stars.
2. Describe the nature of spiral arms in terms of stars and the inter-stellar medium. Explain its importance in terms of star formation.
3. Calculate the mass of the Galaxy.
4. Describe the three types of normal galaxies in the Universe, and explain how they are different.
5. Explain how galaxies evolve through stellar evolution and mergers. Describe the Black Hole Model for active galactic nuclei and quasars.
6. Describe the large-scale structure of the Universe, starting with the Local Group of galaxies and including galaxy clusters. Explain how the distances to other galaxies are determined.
7. Explain the observations leading to the concepts of the expansion of the universe, the Hubble Constant, and the Big Bang Model.
8. Describe the microwave background and other tests of cosmological models. Describe the problems of the Big Bang model.
9. Describe the sequence of events in the Big Bang Model of the evolution of the Universe, and the possible fates of the Universe.
