A Radio Pulsar/X-ray Binary Link
Anne M. Archibald, Ingrid H. Stairs, Scott M. Ransom +15
Radio pulsars with millisecond spin periods are thought to have been spun up by transfer of matter and angular momentum from a low-mass companion star during an X-ray-emitting phas…
The GBT 350-MHz Drift Scan Pulsar Survey. III. Detection of a magnetic field in the eclipsing material of PSR J2256-1024
Kathryn Crowter, Ingrid H. Stairs, Christie A. McPhee +11
We present the first measurement of a non-zero magnetic field in the eclipsing material of a black widow pulsar. Black widows are millisecond pulsars which are ablating their compa…
A Population of Non-Recycled Pulsars Orginating in Globular Clusters
Ryan S. Lynch, Duncan R. Lorimer, Scott M. Ransom +1
We explore the enigmatic population of long-period, apparently non-recycled pulsars in globular clusters, building on recent work by Boyles et al (2011). This population is difficu…
A 1.05 Companion to PSR J2222-0137: The Coolest Known White Dwarf?
David L. Kaplan, Jason Boyles, Bart H. Dunlap +5
The recycled pulsar PSR J2222-0137 is one of the closest known neutron stars, with a parallax distance of pc and an edge-on orbit. We measure the Shapiro delay…
Spectroscopy of the inner companion of the pulsar PSR J0337+1715
David L. Kaplan, Marten H. van Kerkwijk, Detlev Koester +5
The hierarchical triple system PSR J0337+1715 offers an unprecedented laboratory to study secular evolution of interacting systems and to explore the complicated mass-transfer hist…
The Green Bank Telescope 350 MHz Drift-scan Survey I: Survey Observations and the Discovery of 13 Pulsars
Jason Boyles, Ryan S. Lynch, Scott M. Ransom +17
Over the summer of 2007, we obtained 1191 hours of `drift-scan' pulsar search observations with the Green Bank Telescope at a radio frequency of 350 MHz. Here we describe the surve…
Young Radio Pulsars in Galactic Globular Clusters
Jason Boyles, Duncan R. Lorimer, Phil J. Turk +5
Currently three isolated radio pulsars and one binary radio pulsar with no evidence of any previous recycling are known in 97 surveyed Galactic globular clusters. As pointed out by…
Discovery of Five New Pulsars in Archival Data
Mitchell B. Mickaliger, Duncan R. Lorimer, Jason Boyles +7
Reprocessing of the Parkes Multibeam Pulsar Survey has resulted in the discovery of five previously unknown pulsars and several as-yet-unconfirmed candidates. PSR J0922-52 has a pe…
The hunt for new pulsars with the Green Bank Telescope
Ryan S. Lynch, Anne M. Archibald, Shawn Banaszak +33
The Green Bank Telescope (GBT) is the largest fully steerable radio telescope in the world and is one of our greatest tools for discovering and studying radio pulsars. Over the las…
The Green Bank Telescope 350 MHz Drift-scan Survey II: Data Analysis and the Timing of 10 New Pulsars, Including a Relativistic Binary
Ryan S. Lynch, Jason Boyles, Scott M. Ransom +17
We have completed a 350 MHz drift scan survey using the Robert C. Byrd Green Bank Telescope with the goal of finding new radio pulsars, especially millisecond pulsars that can be t…
The Green Bank North Celestial Cap Pulsar Survey III: 45 New Pulsar Timing Solutions
Ryan S. Lynch, Joseph K. Swiggum, Vlad I. Kondratiev +37
We provide timing solutions for 45 radio pulsars discovered by the Robert C. Byrd Green Bank Telescope. These pulsars were found in the Green Bank North Celestial Cap pulsar survey…
New timing solutions for Rotating Radio Transients
Bingyi Cui, Jason Boyles, Maura McLaughlin +1
The rotating radio transients are sporadic pulsars which are difficult to detect through periodicity searches. By using a single-pulse search method, we can discover these sources,…
