Abstract / Description: 

The past few years have seen a tremendous increase in the scale of galaxy surveys measuring the large scale structure of the universe. Photometric galaxy surveys are now routinely probing the dark matter clustering through the weak lensing technique, while spectroscopic surveys do the same through the redshift space distortions technique. Baryonic acoustic oscillation measurements are determining distances as a function of redshift, allowing one to measure the matter density and the Hubble parameter. In combination with the cosmic microwave background, these data sets are providing invaluable information on the origins of the structure in our universe, its geometry, age, matter content, neutrino properties, and other fundamental properties of our universe. Without trying to be comprehensive, this colloquium will describe some recent advances in the field, and ponder possible directions for the future.


 

Held Tuesdays at 4:30 pm in the William R. Hewlett Teaching Center, room 201.

Refreshments in the lobby of Varian Physics at 4:15 pm.
