SZE+Optical Studies of the Cosmic Acceleration

Blanco Cosmology Survey (BCS) was a 60 night NOAO survey program on the Blanco 4m from 2005-2008 to study the cosmic acceleration using two different techniques. The first is a galaxy cluster survey in coordination with mm-wave surveys like APEX, ACT and SPT. The second is using the galaxy power spectrum to measure cosmological distances out to redshift z~1.

We used the MOSAIC II imager to carry out a deep, four band (griz) photometric survey of two 50 deg2 patches of the southern sky. These two fields were centered at:

23h00m,-55o12m and 05h30m,-52o47m

More details on the BCS survey including data acquisition, processing, calibration and data release can be found in the BCS survey paper "The Blanco Cosmology Survey: Data Acquisition, Processing, Calibration, Quality Diagnostics and Data Release" (ApJ 757, 83 (2012)) on arxiv. We request that this paper be referenced by people who use these data. Please read NOAO policies on Acknowledgement and Conditions of Use.
