GBT 350-MHz Driftscan Survey Processing

This page lists the new pulsars discovered in our drift-scan survey with the GBT at 350 MHz. There have been 16 new pulsars including 2 MSPs found so far!

The 350-MHz drift-scan survey has produced about 134 Tb (1491 observing hours) of data. This survey took advantage of the track refurbishing done over the summer of 2007 and covered about 12000 square degrees of the sky between declinations of -21 and 26 degrees. The surveyed area contains 459 known pulsars, with many pulsars redetected thus far.

The first pulsar discovered was J1736-02, also the first millisecond pulsar detected. Follow-up observations were performed on the first nine discoveries on June 17th. All pulsars except J1625-08 were found in the confirmation search with a FFT. J1625-08 was detected in the single pulse search in the confirmation observations.

New discoveries J1502+00 and J0459-05 still need to be confirmed. PSRs J1845-07, J1918-10, and J1941+01 were confirmed in our last observation on Sept. 3rd. PSR J0459-05 falls outside of our current LST range and has therefore not been observed. All other discovered pulsars have been confirmed. All but J1625-08 have been observed at both 350 and 820 MHz. See new pulsars for more details.

A timing proposal was submitted and accepted for the February 1st deadline for the GBT to start the follow-up timing of these newly discovered pulsars. A second proposal was submitted on the June 2nd deadline for timing.

An exploratory proposal has been submitted for the 08-C trimester. We have been given the eight hours requested by this proposal .

The date list of the table tells when a new pulsar has been discovered. The institution list tells where the data are for each detected pulsar.

The collaboration includes members from Australia Telescope National Facility, Cornell University, McGill University, National Radio Astronomy Observatory, Universiteit van Amsterdam, University of British Columbia, University of Virginia, University of California at Berkeley, University of Texas at Brownsville, and West Virginia University.
