The Galaxy-mass Correlation Function Measured from Weak Lensing in the Sloan Digital Sky Survey
We present galaxy-galaxy lensing measurements over scales 0.025 to 10 h 1 Mpc in the Sloan Digital Sky Survey (SDSS). Using a flux-limited sample of 127,001 lens galaxies with spectroscopic redshifts and mean luminosity hLi L and 9,020,388 source galaxies with photometric redshifts, we invert the lensing signal to obtain the galaxy-mass correlation function gm. We find gm is consistent with a p...

We present galaxy-galaxy lensing measurements over scales 0.025 to 10 h Mpc in the Sloan Digital Sky Survey. Using a flux-limited sample of 127,001 lens galaxies with spectroscopic redshifts and mean luminosity 〈L〉 ∼ L∗ and 9,020,388 source galaxies with photometric redshifts, we invert the lensing signal to obtain the galaxy-mass correlation function ξgm. We find ξgm is consistent with a power...
متن کاملThe Correlation Function of Optically Selected Galaxy Clusters in the Sloan Digital Sky Survey
We measure the two-point spatial correlation function for clusters selected from the photometric MaxBCG galaxy cluster catalog for the Sloan Digital Sky Survey (SDSS). We evaluate the correlation function for several cluster samples using different cuts in cluster richness. Fitting the results to power-laws, ξcc(r) = (r/R0) , the estimated correlation length R0 as a function of richness is broa...
متن کاملBivariate galaxy luminosity functions in the Sloan Digital Sky Survey
Bivariate luminosity functions (LFs) are computed for galaxies in the New York Value-Added Galaxy Catalogue, based on the Sloan Digital Sky Survey Data Release 4. The galaxy properties investigated are the morphological type, inverse concentration index, Sérsic index, absolute effective surface brightness (SB), reference frame colours, absolute radius, eClass spectral type, stellar mass and gal...
متن کاملThe Sloan Digital Sky Survey
The Sloan Digital Sky Survey (SDSS) will carry out a digital photometric and spectroscopic survey over π steradians in the northern Galactic cap. An array of CCD detectors used in drift-scan mode will image the sky in five passbands to a limiting magnitude of r′ ∼ 23. Selected from the imaging survey, 10 galaxies, 10 quasars and selected samples of stars will be observed spectroscopically. In a...
