Fast Radio Bursts are enigmatic, millisecond-long, bright (typically 1-100 Jy) radio flashes of (mostly) cosmological origin (up to z ~ 2). At the time of writing, a few hundreds of events have been observed with a large range of properties in terms of fluences, spectra, time smearing and characteristics of the host galaxies - when localized. Their origin remains indeed largely debated,...
Gamma-Ray Bursts (GRBs) are the most powerful explosions in the Universe. They are thought to be generated by the collapse of a massive star (long GRBs) or a NS-NS or NS-BH merger (short GRBs). Regardless of the progenitor's nature, a spinning, stellar mass BH or a highly magnetized NS is eventually produced, and this central engine launches a jet of ionized matter which interacts with the...
I will review the possibility to combine galaxy and intensity mapping observations from the SKAO with gravitational waves (GW) detected by laser interferometers. Cross-correlating Large Scale Structure (LSS) data with GWs it will be possible to test the existence and abundance of primordial black holes and perform innovative tests of gravity. Finally, I will explore new ideas for testing the...
