קורס: אסטרופיסיקה כללית 1, 2023

    • A weekly lecture (3 hours) and a weekly tutorial (1 hour regular tutorial 1 hour remedial tutorial).
    • A weekly problem set. Submit all (except maybe one) sets on time to attend the exam.
    • Self-grade your problem set within a week after the solutions are posted; we will sample the grades. Final grade: 80% exam, 20% problem sets.
    • Recorded lectures - announced via e-mail when available

  • Astrophysics. Where Science began... and how it may end.

    1. Elements of radiation, plasma, relativity, nuclear, and particle physics;
    2. Introduction to astronomy: observations, scales, distance ladder;
    3. Stellar structure, formation, collapse and end states;
    4. We, Earth, Solar system, Milky way, local group, visible Universe;
    5. Our galaxy, stellar matter, stellar dynamics, exosolar planets;
    6. Cosmology, Big Bang, structure formation and large scale structure;
    7. Time permitting: high energy astrophysics;
    8. Time permitting: multi-messenger (neutrino, cosmic-ray, gravity waves) astrophysics.
