היקום הדינמי (2022)
על הקורס - כללי
The lectures will be given in English, per the preference of students enrolled.
Homework will include both exercises and reading assignments.
The exam will be take-home, likely in the following format: each student will pick a personal task from a list, will submit a report on it after several weeks and present the results before the class in a meeting to be scheduled.
The course material will be made up of two parts:
1) A short introduction to Astrophysical Fluid Dynamics
- Main: Principles of Astrophysical Fluid Dynamis / Clarke and Carswell, Cambridge University Press
- Astrophysical Flows / Pringle and King, Cambridge University Press
- Elasticity and Fluid Dynamics: Volume III of Modern Classical Physics / Thorne and Blandford, Princeton University Press
2) An introduction to Modern Cosmology:
- An Introduction to Modern Cosmology / Andrew Liddle, 3rd ed., Wiley
- Main: Cosmology Lecture Notes / Daniel Baumann, Link: here
- Modern Cosmology / Scott Dodelson and Fabian Schmidt, 2nd Ed., Elsevier Academic Press
- Cosmology / Steven Weinberg, Oxford University Press
