Timing of Newly Discovered Globular Cluster Pulsars

Abstract

We have acquired GBT data on 13 globular clusters (GCs) at 1.4 GHz in order to search for millisecond, binary and exotic pulsars. Significant computing power has come on-line at both McGill University and Green Bank in December 2001, and our very first search efforts have already yielded 4 new pulsars in our GBT GCs. We propose a series of closely-spaced 4-hour observations on each of 2 clusters to obtain initial phase-connected solutions including orbital parameters, followed by 4-hour observations spaced one to four weeks apart for one year, which will be needed to obtain full timing solutions including position and period derivative measurements.
