Description
Giant pulses (GPs) are very energetic and impulsive phenomena associated with the Crab pulsar, with flux densities up to few MJy and pulse widths ranging from ~100 ns to ~100 µs. GPs observed from the Crab pulsar can be used to study the energy distribution and their dynamic spectra can address the emission mechanisms of neutron stars. In this talk I will present multifrequency observations of the Crab GPs at 408 MHz, 820 MHz and 1400 MHz, carried out with the Northern Cross, Green Bank and Noto telescopes. I will discuss how the GPs energy and arrival time distributions derived from our observations can constrain the physical mechanism responsible for their emission and discuss the connection with the fast radio bursts (FRBs) emission mechanisms. I will conclude my talk by outlining how the SKAO will be able to significantly push forward single pulsars' and population' GP studies and thus drive a better understanding of FRBs emission mechanisms.
