Week 1: Special Relativity
Week 2: More SR + some General Relativity
Week 3: Tidal Forces
Week 4: Effective potentials, Lagrange points, Accretion disks
Midterm 1: (my) review questions
Week 5: Distances, Magnitudes, Dust
Week 6: ISM, Dust
No worksheets this week. We talked about the ISM, HI, HII, molecular H, and observations of galaxies.
Week 7: Rotation curves
Week 8: Dark Matter
No worksheet this week. We talked about evidence for DM, what different types
of DM are (MACHOs, WIMPs), and how we can detect DM (seeing the dynamical effects, indirect
detection, and direct detection). We also talked briefly about the basics of particle physics
-- the particles of the Standard Model, and a bit about how they behave and interact.
I showed a dark matter map made in the COSMOS field using weak gravitational lensing (c. R. Massey/NASA/ESA), and some nice particle physics primer graphics dealing with the Standard Model.
Midterm 2: review questions
Week 9: Galaxies (part I)
No worksheet this week. We reviewed some stuff on the midterm. We also talked about the Faber-Jackson
and Tully-Fisher relations, and how they relate to the distance ladder. We reviewed the
full distance ladder.
Recapped that "early type" galaxy = elliptical, and "late type" galaxy = spiral/disk.
Week 10: Galaxy relations & Dynamical Friction
Week 11: Cosmic Distance Ladder
Week 12: Cosmology: Part I
Mostly we talked about relevant equations and definitions for cosmology, and how the single component (dust/matter only) universe can be extended to cover multiple component universes.
Week 13: Cosmology: Part II
More overview of cosmology, focusing on the important equations: Friedmann equation, acceleration equation, equation of state.
The full, proper manipulation of the Friedmann equation that I was bungling in section is written up in the soln for Prob 1a. Let me know if it's still confusing.
