Seminario

Il giorno 13 novembre alle ore 11,30 presso l'aula 412 Stefano Camera (Universita di Torino) terra' un seminario dal titolo

Fulfilling the promise of multi-tracer cosmology

Abstract

Cross-correlations between various cosmological observables, as well as among cosmological and astrophysical observables, can help us shed new light onto pressing open questions in cosmology. In my talk, I shall touch upon detecting relativistic effects on cosmological scales, novel approaches to probe primordial non-Gaussianity, and cosmological data sets for particle dark matter indirect detection. All this in the view of the new generation of cosmological experiments across the electromagnetic spectrum, like the Euclid satellite and the SKA Observatory. In particular, I shall present the recent first detection of a cosmological 21-cm intensity mapping signal by the MeerKLASS Collaboration, using the SKA South African pathfinder instrument MeerKAT.
