A New Reduction of the Blanco Cosmology Survey: An Optically Selected Galaxy Cluster Catalog and a Public Release of Optical Data Products




  • The Blanco Cosmology Survey is a four-band (griz) optical-imaging survey of ~80 deg2 of the southern sky. The survey consists of two fields centered approximately at (R.A., decl.) = (23h, –55°) and (5h30m, –53°) with imaging sufficient for the detection of L sstarf galaxies at redshift z galaxies at redshift z galaxies at redshift z 85% of which are new discoveries, has a median redshift of z = 0.52 and median richness ?(0.4 L sstarf) = 16.4. Accompanying this paper we also release full survey data products including reduced images and calibrated source catalogs. These products are available at
