We present an analysis of voids in the 2dF Galaxy Redshift Survey (2dFGRS). This analysis includes identification of void regions and measurement of void statistics. The 2dFGRS is the largest completed redshift survey to date, including a total of 245,591 galaxies covering 1500 deg2 to a median depth of zmed ~ 0.11. We use the voidfinder algorithm to identify a total of 289 voids in the 2dFGRS with radius larger than 10 h-1 Mpc. These voids have an average effective radius, the radius of a… Expand
Statistics of voids in the two‐degree Field Galaxy Redshift Survey
We present a statistical analysis of voids in the two-degree Field Galaxy Redshift Survey (2dFGRS). In order to detect the voids, we have developed two robust algorithms. We define voids asExpand
Properties of voids in the 2dFGRS galaxy survey
A method for detecting voids in the galaxy distribution is presented. Using this method, we have identified 732 voids with a radius of the seed sphere Rseed > 4.0h−1 Mpc in a volume-limited sample ofExpand
Voids in the SDSS galaxy survey
Using the method of searching for arbitrary shaped voids in the distribution of volume-limited samples of galaxies from the DR5 SDSS survey, we have identified voids and investigated theirExpand
Void statistics and void galaxies in the 2dF Galaxy Redshift Survey
In the 2dF Galaxy Redshift Survey, we study the properties of voids and of fainter galaxies within voids that are defined by brighter galaxies. Our results are compared with simulated galaxyExpand
Cosmic Voids in Sloan Digital Sky Survey Data Release 7
We study the distribution of cosmic voids and void galaxies using Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using the VoidFinder algorithm as described by Hoyle & Vogeley (2002), weExpand
We study the spectroscopic properties of a sample of 103 void galaxies identified in the Sloan Digital Sky Survey (SDSS) and compare these with the properties of galaxies in higher density regionsExpand
Voids in the 2dFGRS and ΛCDM simulations: spatial and dynamical properties
We perform a statistical study on the distribution and dynamics of voids in the 2dF Galaxy Redshift Survey (2dFGRS). Our statistics are tested and calibrated using mock 2dFGRS catalogues. We analyseExpand
High-redshift voids in the excursion set formalism
Voids are a dominant feature of the low-redshift galaxy distribution. Several recent surveys have found evidence for the existence of large-scale structure at high redshifts as well. We presentExpand
Void galaxies, residing within the deepest underdensities of the Cosmic Web, present an ideal population for the study of galaxy formation and evolution in an environment undisturbed by the complexExpand
The challenge of large and empty voids in the SDSS DR7 redshift survey
We present catalogues of voids for the SDSS DR7 redshift survey and for Millennium I simulation mock data. We aim to compare the observations with simulations based on a $\Lambda$CDM model and aExpand


Automated Detection of Voids in Redshift Surveys
We present a new void search algorithm for automated detection of voids in three-dimensional redshift surveys. Based on a model in which the main features of the LSS of the Universe are voids andExpand
The CfA Redshift Survey: Data for the South Galactic Cap*
We present redshifts for a sample of 4391 galaxies with magnitude mB(0) ≤ 15.5 covering 20h ≤ α ≤ 4h in right ascension and -25 ≤ δ ≤ 90° in declination. This sample is complete for all galaxies inExpand
Voids in Real Space and in Redshift Space
Using two-dimensional numerical simulations of gravitational clustering, with initial power spectra of a power-law form with index n, we compare the properties of voids in real space to theirExpand
A catalogue of the voids in the IRAS 1.2- Jy survey
Using the VOID FINDER algorithm we have compiled a catalogue of voids in the IRAS 1.2-Jy sample. The positions of the voids correspond well to underdense regions seen in the IRAS smoothed densityExpand
Galaxy voids in cold dark matter universes
We present predictions for numerous statistics related to the presence of voids in the distribution of galaxies in a cold dark matter model of structure formation using a semi-analytic model ofExpand
The size and shape of local voids
We study the size and shape of low-density regions in the local Universe, which we identify in the smoothed density field of the PSCz flux-limited IRAS galaxy catalogue. After quantifying theExpand
Voids in the Point Source Catalogue Survey and the Updated Zwicky Catalog
We describe an algorithm to detect voids in galaxy redshift surveys. The method is based on the void finder algorithm of El-Ad & Piran. We apply a series of tests to determine how accurately we areExpand
Voids in the Large-Scale Structure
Voids are the most prominent feature of the large-scale structure of the universe. Still, their incorporation into quantitative analysis of it has been relatively recent, owing essentially to theExpand
A case devoid of bias: Optical Redshift Survey voids versus IRAS voids
We present a comparison between the voids in two nearly all-sky redshift surveys: the Optical Redshift Survey (ORS) and the IRAS 1.2-Jy survey. While the galaxies in these surveys are selectedExpand
The 2dF Galaxy Redshift Survey: luminosity dependence of galaxy clustering
We investigate the dependence of the strength of galaxy clustering on intrinsic luminos- ity using the Anglo-Australian two degree field galaxy redshift survey (2dFGRS). The 2dFGRS is over an orderExpand
