The goal of the project is to explore the possibility of opening new
observational windows on the Early Universe (epochs before Big Bang Nucleosyntesis)
using cosmological magnetic fields, gravitational waves and primordial black holes, all produced by primordial processes and
surviving till the present epoch. We will assess the observational signatures of cosmological magnetic fields in the voids of the large
scale structure and determine which information on their origin can be extracted from multi-messenger observational data (radio,
gamma-ray, ultra-high-energy cosmic ray). The same type of processes leading to primordial magnetic seeds generates gravitational
waves: we will assess their detectability by space-based detectors. We will test different scenarios of primordial black holes
production and their observational signatures in multi-messenger astronomy data. Finally we will investigate the information on
Early Universe physics that can be extracted from the joint detection of these observables.
