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
