Radio Weak Lensing: a new probe for Cosmology with SKA

Marzia Rivi (INAF-IRA)

Tuesday 24/03/2020 @ 14:00, Google Hangouts Meet

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. In this talk I will show how measurement of weak lensing (WL) in the radio band can help to mitigate standard systematics, and present the state-of-the-art of this new research field both in terms of methodologies and results from observational data. Cosmological WL forecasts for SKA Phase 1 will be also presented.
