Single pulse energy distribution of bright radio pulsars observed by parkes radio telescope

Abstract

Pulsars have a very consistent average pulse profile, while individual pulses are varying in intensity for every pulse. The field statistics for the single pulse profile lead to understanding the emission mechanism and the product of pulsar plasma waves emission. This study analyzes the pulse’s energy statistics of 20 bright pulsars in L-band frequency (1.4GHz). The pulse energy statistics for some pulsars are well-defined by Gaussian statistics and some pulsars are well-defined by log-normal statistics. The analysis of the single pulse’s phase variation are varying from Gaussian statistics at the edge of the pulse to log-normal statistics toward the peak of the pulse. These statistics are the tools for understanding the variability of the emission mechanism and characteristics of the pulsars. This work feature the analyzing the phase-resolved energy distribution mode-separately for pulsar J1825-0935.
