Abstract:
In the standard cosmological paradigm, galaxies formed from the small perturbations we observe in the Cosmic Microwave Background. Galaxy clustering provides a probe of the primordial fluctuations, the geometry of the universe, and the scale-dependent suppression of fluctuations by massive neutrinos. I will present cosmological constraints from the final data release of the Sloan Digital Sky Survey, highlighting the impact of improved modeling of the galaxy-dark matter relationship and demonstrating control of systematic modeling errors. I will also show how complementary current low redshift observations further improve constraints on cosmological neutrinos.
