Total Time Requested: 70 Hours
Proposal Title: Timing Measurements of 20 Recently Discovered Pulsars
ABSTRACT:
We propose to measure the standard timing parameters of twenty pulsars discovered by our group
during the Arecibo transit surveys just before and during the upgrade period. Out of the 20 slow pulsars
detected, 11 have not been observed after their discovery, 7 have poorly established spindown rates and
all 20 of them require a much better determination of dispersion measures. In addition, two pulsars have
shown extensive nulling during the initial followup observations and require a closer scrutiny. We request
70 hrs of the telescope time at 430 MHz and 1130 MHz with the Penn State Pulsar Machine, to establish
possibly accurate timing models for all these objects and to investigate their basic emission properties.
