Description
The Crab pulsar is the youngest known neutron star and it has been monitored for over five decades.
Its giant pulses (GPs) provide a unique laboratory for probing neutron-star emission physics. Fast
radio bursts (FRBs), often linked to neutron stars, offer a complementary framework for studying
extreme energy-release processes. Crab GPs have typical fluences larger than a few tens of Jy ms.
They may therefore represent a so far missing link between pulsar physics and repeating FRBs
emission. We conducted observations at 408 MHz with the Northern Cross radio telescope, 820
MHz with the Green Bank Telescope, and 1500 MHz with the Green Bank and Noto telescopes. Our
observations, carried out simultaneously with optical ones, are expected to provide the optical-toradio
energy ratio of Crab giant pulses. I will present the analysis of GPs energy and waiting-time
distributions. I will compare them with those of the most hyperactive repeating FRBs, such as FRB
121101, FRB 201124A, FRB 220114A, and FRB 220912A, including a search for periodicities.
