Seminar Constraining cosmology with the dynamics of voids

Contatto di riferimento: Donatella Romano

Partecipanti: Adam Hawken (INAF, Oss. Astron. Brera/Merate)

Abstract

Voids are the largest component by volume of the cosmic web. As largeunderdense regions they serve as excellent laboratories for testinggeneral relativity. In this seminar I shall give an overview of the searchfor and classification of voids in spectroscopic redshift surveys, inparticular VIPERS. I shall then demonstrate how studies of the crosscorrelation between galaxies and voids can be used to measure the growthrate of structure in simulations, and cover recent attempts to apply thesetechniques to data.
