We present a new galaxy cluster catalog constructed from the Sloan Digital Sky Survey Data Release 9 (SDSS DR9) using an Adaptive Matched Filter (AMF) technique. Our catalog has 46,479 galaxy clusters with richness Λ200 > 20 in the redshift range 0.045 z < 0.641 in ~11,500 deg2 of the sky. Angular position, richness, core and virial radii and redshift estimates for these clusters,...
