4.5.3 New Discoveries: Non-Repeating Sources

In addition to the confirmed sources described here we have identified a number of candidates which we deem to be ‘self-confirmed’, i.e. we have not re-observed bursts in a followup observation but we deem the survey detection sufficiently convincing that the astrophysical nature of these sources is clear. A number of these are just single bursts, show the characteristic dispersive delay expected from celestial sources, are detected in only one beam and show no signatures of RFI. Figures 4.14 and 4.15 show DM–time search output and frequency-time plots showing the dispersive sweep of individual pulses, for some of these sources. We can see that these sources obey the theoretical dispersion law of Eq. 4.23.
