Einstein@Home pulsar discoveries in Parkes Multibeam Survey data

Background

Einstein@Home is currently re-analysing the Parkes Multibeam Survey (PMsurv) data. Observations of 35 minutes length are coherently searched for radio pulsars in binary systems. This is the first search of this data set using coherent binary search methods over the full observation time of each beam.

Results

So far, the Einstein@Home-PMsurv re-analysis has found ten new pulsars, which were confirmed with recent observations. The properties of the pulsars in the PMsurv discovery beams are listed in the table below.
