Investigating New Transient Radio Sources

We have discovered a new class of transient radio sources from a single pulse search of the Parkes Multibeam Pulsar Survey data. Of the twelve new sources, two are in the Arecibo declination range. For one of these two ob jects, we are able to measure a period and period derivative, indicating a neutron star origin. Our analysis relies on the single pulses themselves as this source is not detectable through its time-averaged emission. Arecibo observations will allow us to constrain the amplitude distribution of the pulses from this ob ject and to determine its relationship to known radio pulsars. The other of the new ob jects is a more sporadic emitter, with only four pulses detected at four different epochs. Arecibo observations are crucial for localizing the source, determining the amplitude distribution of the pulses, and understanding the nature of this unusual bursting ob ject.
