This course covers the various celestial bodies that exist in the universe, such as stars and galaxies, as well as their structure, birth, and evolution. Thanks to developments in observing the universe in recent years, in particular the operation of space telescopes, our understanding of celestial phenomena has advanced in leaps and bounds. We will cover various celestial phenomena, in connection with the latest observational results. We will also cover the radiative process of electromagnetic waves and particles necessary for understanding these kinds of celestial phenomena.
The goal of this course is to utilize knowledge in mechanics, electromagnetism, thermal and statistical mechanics, quantum mechanics, etc. learned up to this point to explain our view of the universe based on the latest observations from a physics viewpoint.
At the end of this course, students will be able to
1) Explain underlying physics of the various phenomena in the universe.
2) Explain the phenomena revealed by the latest space observations.
3) Explain characteristics of black-body radiation, spectral line emission from atoms and ions, and non-thermal emission, which are important to understand the universe.
