Description
Cosmic voids are the biggest large scale structure of the universe, whose evolution is
sensitive to cosmological parameters. In particular, it is possible to study their auto-
correlation function, or cross-correlate their distribution with other cosmological
observables, such as the CMB, the galaxy distribution or the weak gravitational lensing.
In this talk I will present the forecast on the measurement of the neutrino mass scale and
the Dark Energy equation of state, obtained from the void-lensing cross-correlation applied
to ESA survey, Euclid. The result indicates that this observable allows to enhance the
measurement of these parameters, and consequently the Euclid performance.
