We perform a comprehensive redshift-space distortion
analysis based on cosmic
voids in the large-scale distribution of galaxies observed with the SDSS DR12 data.
We measure multipoles of the void-galaxy cross-correlation function and compare
them with standard model predictions in cosmology. We constrain the growth rate of structure with a precision that is competitive with state-of-the-art
galaxy-clustering results.
