Cosmology

Cosmology. We can simulate how a nearly smooth distribution of dark matter turns into our lumpy, grainy Universe with its hierarchy of structures - from galaxies to superclusters, great walls and voids. We can “ see ” some of the dark matter through gravitational lensing.

Presentation Transcript

  1. Cosmology

  2. We can simulate how a nearly smooth distribution of dark matter turns into our lumpy, grainy Universe with its hierarchy of structures - from galaxies to superclusters, great walls and voids We can “see” some of the dark matter through gravitational lensing New results also indicate that we have dark energy in addition to dark matter, accelerating the expansion of the universe

  3. “Acoustic” spectrum of CMB TemperaturePower   Angular scale

  4. Large Scale Structure of Universe • The Universe is expanding… • Hubble Constant H0 = 70 km/s/Mpc = 1/14Gyr • …initially it was filled with a smooth distribution of dark matter • and a smaller amount of nucleons + electrons • very small initial density fluctuations… • …which began to clump to create the seeds of filaments, superclusters, walls, … , galaxies (central black holes?)

  5. Detailed map of dark matter

  6. Geometry of Universe?

  7. Universe is 70% dark energy! What is the Universe made of?
