  1. Cosmology = Big Questions • What is the universe made of • How does it evolve • How do galaxies, stars and planets form • How do they evolve • What Laws of physics in extreme conditions • What are the origins and properties of the energetic particles reaching the Earth • Can we learn in earthbound laboratories about the beginning and evolution of the Universe • OR …..

  2. What do you need to UNDERSTAND this picture? What do you need to TEACH this subject ?

  3. Proposal COSMOLOGY (overview) • Basic Astronomical topics • Important General Notions • Big Bang & Proof of Expansion • Cosmic Rays • Cosmic pizza • Proof of existence Dark Matter • Proof of existence Dark Energy • Relations with Particle Physics One-week programme / HST 2006

  4. Proposal COSMOLOGY (overview) Clear distictions: What is really scientific proven What is on serious scientific debate What is speculation What is a real important mystery Sources of good information One-week programme / HST 2006

  5. Proposal COSMOLOGY (1/8) 1 = Basic Astronomy topics Olberts paradox Spectra and Redshift Evolution of stars Hertzsprung Russel diagram Cosmological distance ladder Structure of Universe One-week programme / HST 2006

  6. Proposal COSMOLOGY (2/8) 2 = Important general notions (preconditions): A = Relations between - Temperature & Particles - Temperature & Radiation (black body) B = Relativity and bending of space One-week programme / HST 2006

  7. Proposal COSMOLOGY (3/8) • 3 = Big Bang & Proof of the Expansion • What is ment by Big Bang (misconceptions !) • Hubble’s Law • Microwave background (explain importance) • experimental fact ( serendipity ! ) • cooled black box radiation ( mysterious theory ) • Abundance of light elements (explain importance) • * related to the inflation period of the universe One-week programme / HST 2006

  8. Proposal COSMOLOGY (4/8) 4 = Cosmic Ray Research Types of cosmic rays Ways to detect CR Spectrum UHECR mystery Scientific and School projects One-week programme / HST 2006

  9. Proposal COSMOLOGY (5/8) 5 = New Physics: “mysteries of the COSMIC PIZZA” Dark Matter Dark Energy One-week programme / HST 2006

  10. Proposal COSMOLOGY (6/8) • 6 = DARK MATTER • How do we know its existence ? • Rotation of Galaxies • Gravitational Lensing • Explanation • Measuring • Way of clustering on a large scale • (optional: different candidates DM) One-week programme / HST 2006

  11. Proposal COSMOLOGY (7/8) • 7 = Dark Energy • How do we know of its existence? • How do we know the amount of BE? • New increasing accelleration • Proof by SN-1a One-week programme / HST 2006

  12. Proposal COSMOLOGY (8/8) 8 = Relations: Cosmology & Particle Physics Overview relation Time Temperature Condensation Energy in Particle LHC = looking at the beginning of the Universe What does that mean ?? One-week programme / HST 2006
