The Clustering of Galaxy Groups: Dependence on Mass and Other Properties
We investigate the clustering of galaxy groups and clusters in the SDSS using the Berlind et al. (2006) group sample, which is designed to identify galaxy systems that each occupy a single dark matter halo. We estimate group masses from their abundances, and measure their relative large-scale bias as a function of mass. Our measurements are in agreement with the theoretical halo bias function, ...
متن کاملProperties of Galaxy Groups in the SDSS: I.– The Dependence of Colour, Star Formation, and Morphology on Halo Mass
Using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey (SDSS DR2), we investigate the correlation between various galaxy properties and halo mass. We split the population of galaxies in early types, late types, and intermediate types, based on their colour and specific star formation rate (SSFR). At fixed luminosity, the late (early) type fraction of galaxies increas...
متن کاملHigher-Order Angular Galaxy Correlations in the SDSS: Redshift and Color Dependence of non-Linear Bias
We present estimates of the N-point galaxy, area-averaged, angular correlation functions ω̄N(θ) for N = 2,...,7 for galaxies from the fifth data release of the Sloan Digital Sky Survey. Our parent sample is selected from galaxies with 18 ≤ r < 21, and is the largest ever used to study higher-order correlations. We subdivide this parent sample into two volume limited samples using photometric red...
متن کاملTHE DEEP2 GALAXY REDSHIFT SURVEY: COLOR AND LUMINOSITY DEPENDENCE OF GALAXY CLUSTERING AT z 1
Wepresentmeasurements of the color and luminosity dependence of galaxy clustering at z 1 in theDEEP2Galaxy Redshift Survey. Using volume-limited subsamples in bins of both color and luminosity, we find the following: (1) The clustering dependence is much stronger with color than with luminosity and is as strong with color at z 1 as is found locally. We find no dependence of the clustering ampli...
متن کاملGalaxy Groups in the Sdss Dr4: Iii. the Luminosity and Stellar Mass Functions
Using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) with an adaptive halo-based group finder, we investigate the luminosity and stellar mass functions for different populations of galaxies (central versus satellite; red versus blue; and galaxies in groups of different masses) and for groups themselves. The conditional stellar mass functio...
