Astronomy 101 Final Exam (150 pts.) New Material Lecture & Book: - Review material starting on detection of black holes, like Cygnus X-1, and production of the X-rays (model—Apr. 24), Hubble’s discoveries, characteristics of galaxies, the Milky Way galaxy through Cosmology and the Big Bang Theory, and extraterrestrial life. Discussion: You studied Cygnus X-1, galaxy types, 21 cm radiation, how black holes produce X-rays, and cosmology topics. Lab: Since last exam, Labs Homework #5: solutions on web page after May 8 Lecture: There will be more lecture activity papers. New material and things you should be able to explain/describe: Review accretion disk models for both supermassive (like at the center of a galaxy or quasar) and regular black holes (like Cygnus X-1). What is Hubble's Law/Diagram? How do astronomers use Hubble’s law? Expansion of the Universe Where does this idea come from? What does it really mean? What doesn’t it mean?
