Cosmology Cosmological principle Universal expansion – v = Hod Newtonian Universe – 3 possible cases (k, Ω, q) -open, closed, borderline/marginally bound Critical density - Ω = ρ/ρcrit GR in Cosmology – curvature of space (κ, Ω) Cosmological redshift – λo/λ = 1/R(t) = 1 + z Cosmological constant - let ρ = ρ – Λ/8πG Age of Universe for different curvatures (Λ=0) Is the Universe open, closed, flat? Results from. .. - adding up matter - gravitational effects (change of Ho over time) – Accelerating Universe! - measuring flatness Ωtot = ΩM + ΩΛ Big Bang CMB – what, when where. .. (Decoupling/Recombination), importance to BB Radiation/Matter dominated Universe CMB Anisotropies (geometry of universe, seeds of structure, etc) CMB questions (horizon problem, flatness problem) 2nd Exam Review Exam date & time: Tuesday, April 19th from 8:30am to 10:30am

Unformatted text preview: baryonic matter is ~5% of ρcrit Basic fundamental particles – leptons, hadrons, baryons, quarks Four fundamental forces – relative strengths and particle carriers – Unification theory Inflation – how does it solve CMB questions? Planets Terrestrial vs. Jovian planets Comets Meteoroids, Asteroids Formation of Solar System – Nebular Theory and Condensation Theory Terrestrial planets – compare interior structure, rotation rates, axis tilts Earth - atmosphere, magnetosphere, ocean tides Moon – cratering, formation Mercury –no atmosphere, craters Venus – thick atmosphere, volcanoes Mars – thin atmosphere, moons, space craft visits, surface features, volcanoes, water Jovian planets – compare interior structure, rotation rates, axis tilts, atmospheres Jupiter’s zones, belts, Great Red Spot Saturn, Uranus, Neptune – atmosphere differences Pluto Kuiper Belt Extrasolar Planets...
