The Green Bank North Celestial Cap Pulsar Survey: Status and Future

Abstract

The ongoing Green Bank North Celestial Cap pulsar survey is using the Green Bank Telescope to search for pulsars and transients over 85% of the celestial sphere. The survey has resulted in over 150 new pulsars, among which are high-precision millisecond pulsars, several binary pulsars, including at least one relativistic double neutron star system, nulling pulsars, and several nearby millisecond pulsars. We find no fast radio bursts in the survey to date. We present these results and discuss the future prospects for the survey.

Radio Pulsar Populations

“…Our understanding of the Galactic population of MSPs and, more generally, recycled pulsars over the past decade has been significantly improved. This is thanks, in large part, to a great increase in sample size provided by a number of large-scale surveys of the Galactic disk at Parkes [46], Green Bank [47], Arecibo [48], Effelsberg [49] and the Low-Frequency Array [50]. These surveys have greatly increased the sample size such that the number of Galactic MSPs now outnumbers their counterparts in globular clusters.…”

Shanghai Tianma Radio Telescope and Its Role in Pulsar Astronomy

“…A large-aperture telescope is indispensable for detecting such weak signals and for in-depth studies. Using the largest radio telescopes in the world, such as the Arecibo (305 m) [23], the Green Bank Telescope (100 m) [24,25], the Effelsberg (100 m) [26], the Lovell (76 m) [27], and the Parks (64 m) [28], pulsar researchers have achieved a series of important results. The newly built Five-Hundred-Meter Aperture Spherical Telescope (500 m) in China, which is the largest single-dish telescope in the world, has also become a sharp tool to obtain more and more important research results on pulsars [29][30][31][32].…”
