Resumen:
We designed a version of the Alcock-Paczyński cosmological test using the void-galaxy cross-correlation function in redshift space. For this purpose, we developed a model that reproduces the geometric and dynamical distortions observed on the correlation isocontours, which allow to extract cosmological information. The model fundamentally depends on the matter density parameter, , and the redshift of the voids, . In order to calibrate the test, we used the Millennium XXL Simulation. Specifically, we evaluated the sensitivity of the fitting process as a function of redshift covering a wide range: , in view of the depth of the new generation of galaxy surveys.
