Bivariate 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...
متن کاملThe Sloan Digital Sky Survey
The Sloan Digital Sky Survey is an ambitious, multi-institutional project to create a huge digital imaging and spectroscopic data bank of 25% of the celestial sphere, approximately 10,000 deg2 centred on the north galactic polar cap. The photometric atlas will be in 5 specially-chosen colours, covering the π ster of the Survey area to a limiting magnitude of r′∼23.1, on 0′′ . 4 pixels, resultin...
متن کاملGalaxy clustering in the Sloan Digital Sky Survey (SDSS): A first comparison with the APM Galaxy Survey
We compare the large scale galaxy clustering in the new SDSS early data release (EDR) with the clustering in the old APM Galaxy Survey. We make equal area projection pixel maps, similar to the ones used in the APM analysis to allow a direct comparison between the clustering in the two samples. We concentrate our analysis on an equatorial SDSS strip, 2.5 wide and 66 degrees long. Galaxies with P...
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...
