Continuing a Pilot GBT Pulsar Survey of the Galactic Plane

Abstract

We propose to continue a pilot pulsar survey of the Galactic plane in a 25 square-deg region (5deg<=l<=10deg, 5<=b<= 10deg). We optimistically expect to discover 14+/-3 new pulsars in this pilot project, making it a worthwhile endeavor in its own right. We have an additional goal of empirically validating simulations suggesting that a larger GBT L-Band Galactic plane survey could discover ~500 new pulsars, ~50 of which would be millisecond pulsars. If these estimates are accurate then such a pulsar survey would be among the most successful ever performed, but radio frequency interference and other difficult-to-model effects are likely to reduce the actual yield, perhaps substantially. The pilot program that we propose here will allow us to confidently and optimally design a future large survey. We have thus far collected 1.5 hours of survey data, which has allowed us to test our data reduction pipeline. Continuing the pilot survey, and eventually completing a larger survey, will help to answer many outstanding questions in pulsar astronomy.
