Pulse profiles and a stack of individual pulses for three Rotating Radio Transients observed with Murriyang.
A study of 10 Rotating Radio Transients using Murriyang, the Parkes radio telescope
by Ren et al.
Rotating Radio Transients (RRATs) are a subclass of pulsars that emit detectable radio bursts only sporadically. Ren et al. conducted an analysis of 10 RRATs observed using Murriyang, the Parkes telescope, with 8 of these observed using the Ultra-Wideband Low receiver. Single-pulses were detected in 3 RRATs (PSRs J1919+1745, J1909+0641 and J0628+0909). The integrated profiles of the entire observations for these 3 RRATs are shown in upper panels above, in which the on-pulse and off-pulse regions are shown in filled blue and gray areas, respectively. The lower panels show a single-pulse stack of 15 single pulses for each RRAT, in which the burst pulses are shown as solid red lines. The average burst rate of PSR J1919+1745 is one burst per 847 hours, much larger than that of both PSR J0628+0909 (one burst per 60 hours) and PSR J1909+0641 (one burst per 58 hours). The analysis shows that PSRs J1919+1745, J1709-43 and J1649-4653 are potentially nulling pulsars or weak pulsars with sparse strong pulses.
