Title: Precision cosmology with cosmic voids
Abstract:Modern surveys provide access to high-quality measurements on large areas of the sky, sampling the galaxy distribution in detail also in the emptiest regions, voids. Void cosmology is becoming an increasingly active sector of galaxy clustering analysis: by measuring void properties, such as void density profiles or the void-size function, it is possible to constrain cosmological parameters. Voids are particularly sensitive to the properties of dark energy and neutrinos, and are a powerful tool to test modifications of the laws of general relativity. In this talk I illustrate the use of cosmic voids as a tool for cosmology, I present recent results and discuss future developments in the field.
