Title: Standard rods when making maps

Date: Wednesday, October 15th, 2008
Time: 12:00
Venue: Villa Bazzoni

***********************************************************
Abstract:
The baryon acoustic oscillation signal in the galaxy distribution provides a standard rod which can be used to constrain models of the dark energy equation of state. These constraints depend on just how standard, or standardizable, this rod is. I will review the measurements to date, for which the rod is rigid enough, and will then describe efforts to standardize the rod for use in the next generation of maps.
