Query: Narrow-band giant pulses from the Crab pulsar   We used a new spectral-fitting technique to identify a subpopulation of 6
narrow-band giant pulses from the Crab pulsar out of a total of 1578. These
giant pulses were detected in 77 minutes of observations with the 46-m dish at
the Algonquin Radio Observatory at 400-800 MHz. The narrow-band giant pulses
consist of both main- and inter-pulses, thereby being more likely to be caused
by an intrinsic emission mechanism as opposed to a propagation effect. Fast
Radio Bursts (FRBs) have demonstrated similar narrow-band features while only
little has been observed in the giant pulses of pulsars. We report the
narrow-band giant pulses with $\Delta \nu / \nu$ on the order of 0.1, which is
close to the value of 0.05 reported for the repeater FRB 20190711A. Hence, the
connection between FRBs and giant pulses of pulsars is further established.
