The Sloan Digital Sky Survey-II Supernova Survey: Technical Summary
Joshua A. Frieman, B. Bassett, A. Becker +98
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (…
Modeling the three-point correlation function
Felipe Marin, Risa Wechsler, Joshua Frieman +1
We present new predictions for the galaxy three-point correlation function (3PCF) using high-resolution dissipationless cosmological simulations of a flat LCDM Universe which resol…
Chandra Observations of SDSS J1004+4112: Constraints on the Lensing Cluster and Anomalous X-Ray Flux Ratios of the Quadruply Imaged Quasar
N. Ota, N. Inada, M. Oguri +15
We present results from Chandra observations of SDSS J1004+4112, a strongly lensed quasar system with a maximum image separation of 15". All four bright images of the quasar, as we…
Early-type galaxies in the SDSS. I. The sample
M. Bernardi, R. K. Sheth, J. Annis +7
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01 < z < 0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria. This pa…
Galaxy Mass and Luminosity Scaling Laws Determined by Weak Gravitational Lensing
Timothy A. McKay, Erin Scott Sheldon, Judith Racusin +18
We present new measurements of scaling laws relating the luminosity of galaxies to the amplitude and shape of their dark matter halos. Early imaging and spectroscopic data from the…
Weak Lensing and the Sloan Digital Sky Survey
Albert Stebbins, Tim Mckay, Joshua A. Frieman
While the strategy for the first applications of weak lensing has been to ``go deep'' it is equally interesting to use one's telescope time to instead ``go wide''. The Sloan Survey…
