Giant micropulse emission in the Vela pulsar at C band
arXiv:2007.03865 · doi:10.3847/1538-4357/aba2e8
Abstract
We present here the analysis of giant micropulses from the Vela pulsar. A total of 4187 giant micropulses with peak flux density 2.5 Jy were detected during almost 4 hours of observations carried out with the Yunnan 40-m radio telescope at 6800 MHz. Nine of the giant micropulses arrived approximately 3 to 4 ms earlier than the peak of average pulse profile, longer than that at lower frequencies. The remaining giant micropulses were clustered into three distributions which correspond to three main emission regions, including four occurring on the trailing edge of averaged profile.
