The Center for Adaptive Optics Treasury Survey (CATS) is observing the deep HST galaxy fields (e.g., GOODS-N and S, COSMOS, GEMS, and EGS) with high-resolution near-infrared imaging from ground-based adaptive optics on large telescopes. Initial results from the first ten Keck laser guide star pointings are presented. Highlights include, 1) H-band (rest-frame R) photometry over maximum of a z=1.32 Type Ia supernova from the HST cluster supernova search of Perlmutter et al. (see poster of Dawson et al.); 2) a near-infrared study of small bulges of distant disk galaxies (z~.6); 3) Stellar population synthesis models of AGN cores to z=1; and 4) Detection of lensed arcs around a z=0.20 cluster. CATS plans its first public data release in Fall 2006. This work is funded by the NSF Science and Technology Center for Adaptive Optics, managed by the University of California at Santa Cruz under the cooperative agreement No. AST-9876783.
