GBT17B-325

Continuing the GBT All-Sky 350-MHz Pulsar Survey

Abstract

We propose to continue the 350-MHz pulsar survey of the entire sky visible from the GBT. The GBNCC (Green Bank North Celestial Cap survey) has grown over the past four years to cover the entire Northern sky down to declinations between +20 to +30 deg, depending on RA as well as the entire Southern sky (down to -40 deg) except for a region between -5 deg to -20 deg. It has used ~4,000hrs of GBT time and has uncovered approximately 150 new pulsars so far. The primary science goal is to discover high-quality millisecond pulsars (MSPs) for NANOGrav and we have contributed 4 MSPs to NANOGrav so far. Simulations of the remaining sky, which are now supported by our data, suggest that we will find tens of new MSPs (we already have eighteen!) and other interesting "recycled" pulsars, and ~200 "normal" pulsars. With 2-min pointings and 75% observing efficiency, we request ~1,400hrs over the next 2.5-3 years to complete the remainder of the survey. The GBNCC is more sensitive by factors of ~5 for slow pulsars and 10-20 for MSPs than previous surveys over much of our survey region.
