Proposal Title: Conrmation of Pulsar Candidates from 430-MHz Drift-Scan Searches
ABSTRACT:
We request 48 hr of telescope time to conrm pulsar candidates discovered in 430-MHz drift-scan search data.
These data were taken by the Berkeley/Cornell and STScI/NAIC collaborations during the latter part of the
upgrade period and are currently being processed on a Beowulf cluster at Jodrell Bank. Processing of these data
began two months ago and is almost 50% complete. In the 550 square degrees covered thus far, we have detected
13 known pulsars, 3 new pulsars (conrmed during our April/May Arecibo session), and 4 candidates which are
almost certainly new pulsars. Of particular interest are pulsars J0610+21 and J1453+19, with periods of 55.6 and
5.79 milliseconds, respectively. We also have roughly 20 candidates which are less likely to be pulsars but do merit
reobservation. We expect to nish the processing of these data by August 2002, at which time we should have a
total of roughly 70 candidates. We request 2 24-hour blocks of time to do conrmation observations and, in
preparation for timing, nd better positions for the new pulsars.
