Isocurvature modes and Baryon Acoustic Oscillations II: gains from combining CMB and Large Scale Structure
Baryon Acoustic Oscillations combining CMB Large Scale Structure
2011/9/29
We consider cosmological parameters estimation in the presence of a non-zero isocurvature contribution in the primordial perturbations. A previous analysis showed that even a tiny amount of isocurvatu...
Redshift-Space Enhancement of Line-of-Sight Baryon Acoustic Oscillations in the SDSS Main-Galaxy Sample

We show that redshift-space distortions of galaxy correlations have a strong e ect on correlation functions with distinct, localized features, like the signature of the Baryon Acoustic Oscillations (B...
