Astrophysics Colloquium: Beth Reid, Lawrence Berkeley National Laboratory, Berkeley: "2D galaxy clustering in SDSS-III BOSS: growth of structure, geometry, and small-scale galaxy motions at z=0.57"
I will summarize results from the first data release (DR9) of SDSS-III BOSS on the growth of structure and expansion history of the universe from measurements of the two-dimensional galaxy clustering at z=0.57, as well as discuss our efforts to improve the modeling of our largest systematic error, the Finger-of-God effect sourced by small-scale galaxy motions.
