Cosmological Constraints from the Anisotropic Clustering Analysis using
  BOSS DR9
  Our observations of the Universe are fundamentally anisotropic, with data
from galaxies separated transverse to the line of sight coming from the same
epoch while that from galaxies separated parallel to the line of sight coming
from different times. Moreover, galaxy velocities along the line of sight
change their redshift, giving redshift space distortions. We perform a full
two-dimensional anisotropy analysis of galaxy clustering data, fitting in a
substantially model independent manner the angular diameter distance D_A,
Hubble parameter H, and growth rate ddelta/dln a without assuming a dark energy
model. The results demonstrate consistency with LCDM expansion and growth,
hence also testing general relativity. We also point out the interpretation
dependence of the effective redshift z_eff, and its cosmological impact for
next generation surveys.
