Description
The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to
measure the scale of baryon acoustic oscillations (BAO) in the
clustering of matter over a larger volume than the combined efforts of
all previous spectroscopic surveys of large-scale structure. BOSS uses
1.5 million luminous galaxies as faint as i = 19.9 over 10,000
deg2 to measure BAO to redshifts z < 0.7. Observations of
neutral hydrogen in the Lyα forest in more than 150,000 quasar
spectra (g < 22) will constrain BAO over the redshift range 2.15 <
z < 3.5. Early results from BOSS include the first detection of the
large-scale three-dimensional clustering of the Lyα forest and a
strong detection from the Data Release 9 data set of the BAO in the
clustering of massive galaxies at an effective redshift z = 0.57. We
project that BOSS will yield measurements of the angular diameter
distance dA to an accuracy of 1.0% at redshifts z = 0.3 and z
= 0.57 and measurements of H(z) to 1.8% and 1.7% at the same redshifts.
Forecasts for Lyα forest constraints predict a measurement of an
overall dilation factor that scales the highly degenerate DA
(z) and H -1(z) parameters to an accuracy of 1.9% at z
~ 2.5 when the survey is complete. Here, we provide an overview of the
selection of spectroscopic targets, planning of observations, and
analysis of data and data quality of BOSS.

This supercomputer simulation, which looks at our cosmic neighborhood from the outside, is a realistic, data-driven reconstruction of the web of dark matter that guided galaxies to their present positions. Where huge dark tendrils cross, bright galaxies cluster; the Virgo cluster alone includes thousands.
