The Cut & Enhance method : selecting clusters of galaxies from the SDSS commissioning data
Tomotsugu Goto, Maki Sekiguchi, Robert C. Nichol +8
We describe an automated method, the Cut & Enhance method (CE) for detecting clusters of galaxies in multi-color optical imaging surveys. This method uses simple color cuts, combin…
Higher Order Moments of the Angular Distribution of Galaxies from Early SDSS Data
István Szapudi, Joshua A. Frieman, Roman Scoccimarro +13
We present initial results for counts in cells statistics of the angular distribution of galaxies in early data from the Sloan Digital Sky Survey (SDSS). We analyze a rectangular s…
The Optical, Infrared and Radio Properties of Extragalactic Sources Observed by SDSS, 2MASS and FIRST Surveys
Z. Ivezic, R. H. Becker, M. Blanton +19
We positionally match sources observed by the Sloan Digital Sky Survey (SDSS), the Two Micron All Sky Survey (2MASS), and the Faint Images of the Radio Sky at Twenty-cm (FIRST) sur…
The Angular Clustering of Galaxy Pairs
Leopoldo Infante, Michael A. Strauss, Neta A. Bahcall +13
We identify close pairs of galaxies from 278 deg^2 of Sloan Digital Sky Survey commissioning imaging data. The pairs are drawn from a sample of 330,041 galaxies with 18 < r^* < 20.…
The Alignment Effect of Brightest Cluster Galaxies in the SDSS
Rita S. J. Kim, Jim Annis, Michael A. Strauss +5
One of the most vital observational clues for unraveling the origin of Brightest Cluster Galaxies (BCG) is the observed alignment of the BCGs with their host cluster and its surrou…
Detecting Clusters of Galaxies in the Sloan Digital Sky Survey I : Monte Carlo Comparison of Cluster Detection Algorithms
Rita S. J. Kim, Jeremy V. Kepner, Marc Postman +15
We present a comparison of three cluster finding algorithms from imaging data using Monte Carlo simulations of clusters embedded in a 25 deg^2 region of Sloan Digital Sky Survey (S…
The Angular Correlation Function of Galaxies from Early SDSS Data
SDSS Collaboration, Andrew Connolly, Ryan Scranton +22
The Sloan Digital Sky Survey is one of the first multicolor photometric and spectroscopic surveys designed to measure the statistical properties of galaxies within the local Univer…
Analysis of Systematic Effects and Statistical Uncertainties in Angular Clustering of Galaxies from Early SDSS Data
SDSS Collaboration, Ryan Scranton, David Johnston +21
The angular distribution of galaxies encodes a wealth of information about large scale structure. Ultimately, the Sloan Digital Sky Survey (SDSS) will record the angular positions…
Galaxy Number Counts from the Sloan Digital Sky Survey Commissioning Data
Naoki Yasuda, Masataka Fukugita, Vijay K. Narayanan +10
We present bright galaxy number counts in five broad bands () from imaging data taken during the commissioning phase of the Sloan Digital Sky Survey (SDSS). The…
Broad Absorption Line Quasars in the Sloan Digital Sky Survey with VLA-FIRST Radio Detections
Kristen Menou, Daniel E. Vanden Berk, Zeljko Ivezic +12
We present 13 Broad Absorption Line (BAL) quasars, including 12 new objects, which were identified in the Sloan Digital Sky Survey (SDSS) and matched within 2'' to sources in the F…
