Voids in the SDSS DR9: observations, simulations, and the impact of the survey mask

We present and study cosmic voids identified using the watershed void finder vide in the Sloan Digital Sky Survey Data Release 9, compare these voids to ones identified in mock catalogues, and assess the impact of the survey mask on void statistics such as number functions, ellipticity distributions...
