Einstein@Home pulsar discoveries in Parkes Multibeam Survey data

Background

Between December 2010 and July 2011, Einstein@Home has re-analysed the Parkes multi-beam 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 24 new pulsars, which were confirmed with recent observations. The properties of the pulsars in the PMsurv discovery beams are listed in the table below.

Info

“pulsar” preliminary pulsar name.
“beam RA”: right ascension of the discovery beam
“beam DEC”: declination of the discovery beam
“Pbary”: barycentric spin period in ms (1-sigma error in parentheses).
“DM”: dispersion measure in pc/cc.
“prepf sig”: significance in sigma from prepfold.
“E@H sgnf”: Einstein@Home significance (S=-log10 (pfA))
“plots”: plots of E@H results and prepfold plot
“volunteers”: the volunteers, whose computers found the new pulsar
“date added”: date when this pulsar was published on this webpage
“notes” contains identifications and other notes: “MSP” stands for “millisecond pulsar”, i.e. a pulsar with a spin period of tens of milliseconds or faster. “binary” pulsars are those that orbit the common centre of mass with a companion star. “intermittent” pulsars show interruptions in their emissions. You can see them switch on and/or off in the course of one observation.
