We present a comparison of the properties of galaxies in the most underdense regions of the Universe, where the galaxy number density is less than 10 per cent of the mean density, with galaxies from more typical regions. We have compiled a sample of galaxies in 46 large nearby voids that were identified using the Sloan Digital Sky Survey DR4, which provides the largest coverage of the sky. We study the u - r colour distribution, morphology, specific star formation rate (SFR) and radial number…

Photometric properties of void galaxies in the Sloan Digital Sky Survey Data Release 7
Using the sample presented by Pan et al., we analyse the photometric properties of 88?794 void galaxies and compare them to galaxies that reside in higher density environments with the same absolute
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 galaxy
The star formation activity in cosmic voids
Using a sample of cosmic voids identified in the Sloan Digital Sky Survey Data Release 7, we study the star formation activity of void galaxies. The properties of galaxies living in voids are
The Galaxy Population In Voids: Are All Voids The Same?
The influence of under-dense environments on the formation and evolution of galaxies is studied by analysing the photometric properties of ~200 galaxies residing in voids, taken from our SDSS DR10
The void galaxy survey: Star formation properties
We study the star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Current star formation rates are derived from H alpha and recent star formation rates from near-UV
Deficit of luminous and normal red galaxies in cosmic voids
We construct a sample of 10 680 wall galaxies and 3064 void galaxies with MR ≲ −20 by cross-referencing a void catalogue from literature with Baryon Oscillation Spectroscopic Survey (BOSS) CMASS
Morphological Segregation in the Surroundings of Cosmic Voids
We explore the morphology of galaxies living in the proximity of cosmic voids, using a sample of voids identified in the Sloan Digital Sky Survey Data Release 7. At all stellar masses, void galaxies
Galaxy star formation in different environments
We use a semi-analytic model of galaxy formation to study signatures of large-scale modulations in the star formation (SF) activity in galaxies. In order to do this, we carefully define local and
The Environment of Galaxies at Low Redshift
We compare environmental effects in two analogous samples of galaxies, one from the Sloan Digital Sky Survey (SDSS) and the other from a semianalytic model (SAM) based on the Millennium Simulation
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 their


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 regions
Photometric Properties of Void Galaxies in the Sloan Digital Sky Survey
Using a nearest neighbor analysis, we construct a sample of void galaxies from the Sloan Digital Sky Survey (SDSS) and compare the photometric properties of these galaxies to the population of
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 of

We analyze the optical properties of ~300 galaxies within and around three prominent voids of the Center for Astrophysics Redshift Survey. We determine CCD morphologies and Hα equivalent widths from
The Dependence on Environment of the Color-Magnitude Relation of Galaxies

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 as

Using high resolution N-body simulations we address the problem of emptiness of giant � 20h −1 Mpc–diameter voids found in the distribution of bright galaxies. Are the voids filled by dwarf galaxies?
