Proposal Type: Urgent
General Category: Pulsars

Total Time Requested: 3 Hours
Minimum Useful Time: 1 hour
Proposal Title: Grid and Timing Observations of a Millisecond Pulsar in the direction of the
Virgo Cluster
ABSTRACT:
We request a one-hour grid observation (LST 12:00-13:00) and a separate two-hour timing session (LST
11:40-13:40) of PSR J1239+32, a 4.7 millisecond pulsar in a 4.1-day orbit. This pulsar was recently discovered in
survey observations and is in the general direction of the Virgo galaxy cluster. The latter fact is of potentially great
interest to the pulsar timing array (PTA) projects across the globe for its usefulness in substantially increasing
PTA sensitivity towards gravitational wave signals as discussed in the attached proposal. We therefore request a
total of three hours in order to localize the source in the Arecibo sky and better characterize its spectral and
orbital properties. We will conduct both observations using the L-wide (1400 MHz) Gregorian receiver, and the
PUPPI backend for high-precision data acquisition, for total observing time of three hours.
