We determine the galaxy counts-in-cells distribution from the Sloan Digital Sky Survey (SDSS) for three-dimensional spherical cells in redshift space as well as for two-dimensional projected cells. We find that cosmic variance in the SDSS causes the counts-in-cells distributions in different quadrants to differ from each other by up to 20%. We also find that within this cosmic variance, the overall galaxy counts-in-cells distribution agrees with both the gravitational quasi-equilibrium… Expand

Distribution of Maximal Luminosity of Galaxies in the Sloan Digital Sky Survey
Extreme value statistics (EVS) is applied to the distribution of galaxy luminosities in the Sloan Digital Sky Survey (SDSS). We analyze the DR8 Main Galaxy Sample (MGS), as well as the Luminous RedExpand
Measuring linear and non-linear galaxy bias using counts-in-cells in the Dark Energy Survey Science Verification data
Non-linear bias measurements require a great level of control of potential systematic effects in galaxy redshift surveys. Our goal is to demonstrate the viability of using Counts-in-Cells (CiC), aExpand
The VIMOS Public Extragalactic Redshift Survey (VIPERS) - On the recovery of the count-in-cell probability distribution function
We compare three methods to measure the count-in-cell probability density function of galaxies in a spectroscopic redshift survey. From this comparison we found that when the sampling is low (theExpand
Evolution in the bias of faint radio sources to z 2.2
Quantifying how the baryonic matter traces the underlying dark matter distribution is key to both understanding galaxy formation and our ability to constrain the cosmological model. Using theExpand

The ALHAMBRA survey : Estimation of the clustering signal encoded in the cosmic variance
The relative cosmic variance ($\sigma_v$) is a fundamental source of uncertainty in pencil-beam surveys and, as a particular case of count-in-cell statistics, can be used to estimate the bias betweenExpand
