J/AJ/133/2222     Clustering of high-redshift QSOs from SDSS       (Shen+, 2007)

Clustering of high-redshift (z≥2.9) quasars from the Sloan Digital Sky Survey.

ADC_Keywords: Surveys ; QSOs ; Redshifts ; Photometry Keywords: cosmology: observations - large-scale structure of universe - quasars: general - surveys Abstract: We study the two-point correlation function of a uniformly selected sample of 4426 luminous optical quasars with redshift 2.9≤z≤5.4 selected over 4041deg2 from the Fifth Data Release of the Sloan Digital Sky Survey. We fit a power-law to the projected correlation function wp(rp) to marginalize over redshift-space distortions and redshift errors. File Summary:

Note (1): Objects identified as [SSO2007] DDD.dddddd+DD.dddddd in Simbad. Note (2): Re-measured using line fitting procedures. Note (3): Corrected for Galactic extinction (Schlegel et al., 1998ApJ...500..525S); they use the ubercalibration described by Padmanabhan et al. (2007MNRAS.378..852P), which differs slightly from that used in the official DR5 quasar catalog (Schneider et al., 2007AJ....134..102S). Note (4): The subsample clustering analysis is 1) Selected from the Main SDSS survey with main target selection criteria 2) With target version v310 or later.
