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.
