| 英文摘要 | We have studied 4265 giant pulses (GPs) from the millisecond pulsar B1937+21; the largest-ever sample gathered for this pulsar, in observations made with the Large European Array for Pulsars. The pulse energy distribution of GPs associated with the interpulse are well-described by a power law, with index alpha = -3.99 +/- 0.04, while those associated with the main pulse are best-described by a broken power law, with the break occurring at similar to 7Jy mu s, with power-law indices alpha(low) = -3.48 +/- 0.04 and alpha(high )= -2.10 +/- 0.09. The modulation indices of the GP emission are measured, which are found to vary by similar to 0.5 at pulse phases close to the centre of the GP phase distributions. We find the frequency-resolved structure of GPs to vary significantly, and in a manner that cannot be attributed to the interstellar medium influence on the observed pulses. We examine the distribution of polarization fractions of the GPs and find no correlation between GP emission phase and fractional polarization. We use the GPs to time PSR B1937+21 and although the achievable time of arrival precision of the GPs is approximately a factor of two greater than that of the average pulse profile, there is a negligible difference in the precision of the overall timing solution when using the GPs. |
