Abstract

The NSF National Virtual Observatory (NVO) is a multiyear effort to build tools, services, registries, protocols, and standards that can extract the full knowledge content of massive, multi-frequency data sets. Here we detail our progress from the first year, and plans for the second year of our effort to combine the computational resources of the TeraGrid with the NVO. The work includes: creation of derived image products from multi-terabyte datasets; multiwavelength and multitemporal image federation; analysis of 3-point correlation in galaxies; fitting models to thousands of galaxy spectra; Monte-Carlo modeling of early-Universe models; processing of the ongoing 13 Tbyte Palomar-Quest synoptic survey. TeraGrid impact is broadened through science gateways and grid services, specifically for: exposing massive multi-terabyte datasets through NVO protocols; source extraction and cross-matching; mosaicking, image reprojection and coaddition, as well as authentication mechanisms for such services.
