Abstract:
The Baryonic Acoustic Feature in galaxy clustering is one of the most exciting and promising cosmological distance measurements in modern cosmology. I present clustering measurements of the spherically averaged and line-of-sight acoustic features in the Luminous Red Galaxy sample from the Sloan Digital Sky Survey, as well as what might be expected in the (just begun) Baryonic Oscillation Spectroscopic Survey.
I will also present results obtained from redshift distortions in galaxy clustering. As galaxies are observed in redshift-space, as opposed to real-space, peculiar velocities strongly affect the line-of-sight clustering signal. By quantifying these distortions, constraints on their progenitor, namely the matter density of the universe OmegaM0, may be obtained.
