Presentation Transcript

  1. Dark Matter • Mario LivioSpace Telescope Science Institute

  2. Earth at Night

  3. Cosmic Pie

  4. Structure formation

  5. Neptune vs. Ether Stuff we don’t see Need to change the theory Neptune discovered (1846) as gravitational perturbation to Uranus. The Michelson-Morley experiment (1887).

  6. Bullet Cluster

  7. Source of Dark Matter

  8. Potential Candidates for Dark Matter

  9. Astrophysical Tests of Particle Physics Theories Decay of WIMPs to super-WIMPs may produce photons or electrons which can break light nuclei New “dark” forces would predict clouds of DM to be distorted as they pass through each other

  10. Astrophysical Tests of Particle Physics Theories New force in dark sector (with Sommerfeld enhancement) predicted to produce enhanced leptonic annihilations in substructure in the halo (PAMELA, ATIC)

  11. So far no-show But we’re getting closer!
