The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its Second
Data Release. This data release consists of 3324 deg 2 of five-band (ugriz) imaging data …

The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its First
Data Release. This consists of 2099 deg 2 of five-band (u, g, r, i, z) imaging data, 186,240 …

Weak gravitational lensing allows one to reconstruct the spatial distribution of the projected
mass density across the sky. These “mass maps” provide a powerful tool for studying …

We report the discovery, spectroscopic confirmation, and first lens models of the first, strongly
lensed quasars from a combined search in WISE and Gaia-DR1 over the DES footprint. …

The Grid2003 Project has deployed a multivirtual organization, application-driven grid
laboratory ("Grid3") that has sustained for several months the production-level services required …

We report upon the follow-up of 34 candidate lensed quasars found in the Dark Energy
Survey using NTT EFOSC, Magellan-IMACS, KECK-ESI, and SOAR-SAMI. These candidates …

We use mock galaxy survey simulations designed to resemble the Dark Energy Survey Year
1 (DES Y1) data to validate and inform cosmological parameter estimation. When similar …

The joint analysis of galaxy-galaxy lensing and galaxy clustering is a promising method for
inferring the growth function of large-scale structure. Anticipating a near future application of …

The Sloan Digital Sky Survey (SDSS) data handling presents two challenges: large data
volume and timely production of spectroscopic plates from imaging data. A data processing …

… The branching ratio analysis would not have been possi ble without the groundwork that
was laid by Maurice Foucher in the data analysis, Nickolai Kuropatkin in the Monte Carlo …
