Description
Future cosmological data will improve the constraining power on new physics.
On the one hand, forthcoming CMB data from both ground-based and space-based experiments will allow to get closer to the cosmic variance limit. On the other hand, a completely new window will be opened by the forthcoming facilities that will explore the redshifted 21 cm signal from the Cosmic Dawn.
I will present recent analyses related to both channels and based on WIMP and primordial black hole dark matter as a case study.
Regarding the latter, I will demonstrate in particular the crucial role of the astrophysical uncertainties in assessing the expected constraining power of 21 cm data.
I will conclude emphasizing the complementarity between these two observables as far as new physics searches are concerned.
