The SDSS DR7 Galaxy Angular Power Spectrum
Brett Hayes, Robert Brunner, Ashley Ross
We calculate the angular power spectrum of galaxies selected from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) by using a quadratic estimation method with KL-compressio…
Weak Lensing Measurements of 42 SDSS/RASS Galaxy Clusters
Erin Scott Sheldon, James Annis, Hans Bohringer +21
We present a lensing study of 42 galaxy clusters imaged in Sloan Digital Sky Survey (SDSS) commissioning data. Cluster candidates are selected optically from SDSS imaging data and…
A2125 and its Environs: Evidence for an X-ray-emitting Hierarchical Superstructure
Q. Daniel Wang, Andrew Connolly, Robert Brunner
Based on a deep ROSAT/PSPC observation, we reveal an elongated complex of extended X-ray-emitting objects in and around the galaxy cluster A2125. Multicolor optical imaging of gala…
Workload Analysis of Blue Waters
Matthew D. Jones, Joseph P. White, Martins Innus +12
Blue Waters is a Petascale-level supercomputer whose mission is to enable the national scientific and research community to solve "grand challenge" problems that are orders of magn…
The DEEP Groth Strip Survey. I. The Sample
Nicole P. Vogt, David C. Koo, Andrew C. Phillips +18
The Deep Extragalactic Exploratory Probe (DEEP) is a multi-phase research program dedicated to the study of the formation and evolution of galaxies and of large scale structure in…
Discovery of a Close Pair of z = 4.25 Quasars from the Sloan Digital Sky Survey
Donald P. Schneider, Xiaohui Fan, Michael A. Strauss +17
We report the discovery of a pair of z = 4.25 quasars with a separation of 33 arcseconds. The brighter of the two objects was identified as a high-redshift quasar candidate from Sl…
