Radio Weak Lensing: a new probe for Cosmology with SKA

POSTPONED - Marzia Rivi (IRA)

Tuesday 03/03/2020 @ 14:00, Sala IV piano Battiferro

The new generation radio telescopes, such as the Square Kilometre Array (SKA), are expected to reach sufficient sensitivity to resolve radio emission of ordinary galaxies and therefore provide a large number density. This will lead weak lensing to become one of the primary science drivers in radio surveys too, with the advantage that they will access the largest scales in the Universe going beyond optical surveys, such as LSST and Euclid, in terms of redshifts that are probed, and help to mitigate systematics for such measurement. In this talk I will present the state-of-the-art of this new research field both in terms of methodologies and results from simulated and observational data. Cosmological forecasts for SKA Phase 1 will be finally presented.
