Voids in the 2dFGRS and CDM simulations: spatial and dynamical properties
Voids in the 2dFGRS and CDM simulations: spatial and dynamical properties
We perform a statistical study on the distribution and dynamics of voids in the 2dFGRS. Our statistics are tested and calibrated using mock 2dFGRS catalogues. We analyse the dynamics around voids in mock and real 2dFGRS surveys. The void-galaxy cross-correlation redshift-space distortions show evidence of the continuing growth of voids, …
