Dark Energy from the Largest Galaxy Maps

Dark energy is a phenomena causing the Universe to expand more rapidly than can be explained by Einstein's laws of gravity.  Its discovery merited the 2011 Nobel Prize in Physics.
The effects of dark energy imprint on large galaxy maps.  I will describe the results from the Sloan Digital Sky Survey, which has mapped over a million galaxies and quasars in 3-D, and the future prospects from the BigBOSS project.
