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) pro jects 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.

Remote Observing Request

Observer will travel to AO X Remote Observing In Absentia (instructions to operator)

Instrument Setup
L-wide Atmospheric Observation Instruments:

Sp ecial Equipment or setup: We will use the PUPPI pulsar backend for both observations. This has been fully integrated into the CIMA observing software and is readily usable in pulsar observations 1


RFI Considerations Frequency Ranges Planned
1150-1730 MHz This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz.. This proposal requires coordination with GPS L3 at 1381 MHz.
