A Search for Binary and Millisecond Pulsars in Globular Clusters

Abstract

We propose a high-sensitivity 20 cm search of 6 northern globular clusters for pulsars. Along with conventional "acceleration" and harmonic-summing search techniques, we plan to use a newly developed "phase-modulation" search algorithm that allows the efficient detection of pulsars in extremely compact binaries (including exotic neutron star - neutron star or even neutron star - black hole systems) that were literally impossible to detect before. Long integrations, advanced search algorithms, ample supercomputer time, and the exquisite sensitivity of the GBT will allow at least order-of-magnitude improvements in sensitivity over previous searches.
