Redshift Space Distortions of the Galaxy Distribution
Alex Szalay, John Hopkins University
The talk will present results from analyzing the SDSS Main Galaxy Survey. We will discuss the impact of using unusual geometries in computing the galaxy correlation function. We show that redshift-space distortions can substantially sharpen the BAO peak in directions close to the line of sight. We also demonstrate a detection of Baryon Acoustic Oscillations even in this relatively shallow galaxy sample.
