Spectral and timing properties of the magnetar CXOU~J164710.2-455216
Hongjun An, Victoria M. Kaspi, Robert Archibald +1
We report on spectral and timing properties of the magnetar CXOU J164710.2-455216 in the massive star cluster Westerlund 1. Using 11 archival observations obtained with Chandra and…
X-ray Observations of High-B Radio Pulsars
S. A. Olausen, W. W. Zhu, J. K. Vogel +6
The study of high-magnetic-field pulsars is important for examining the relationships between radio pulsars, magnetars, and X-ray-isolated neutron stars (XINSs). Here we report on…
Deep X-ray Observations of the Young High-Magnetic-Field Radio Pulsar J1119-6127 and Supernova Remnant G292.2-0.5
C. -Y. Ng, V. M. Kaspi, W. C. G. Ho +4
High-magnetic-field radio pulsars are important transition objects for understanding the connection between magnetars and conventional radio pulsars. We present a detailed study of…
The New Magnetar Swift J1822.3-1606
P. Scholz, C. -Y. Ng, M. A. Livingstone +3
On 2011 July 14, a transient X-ray source, Swift J1822.3-1606, was detected by Swift BAT via its burst activities. It was subsequently identified as a new magnetar upon the detecti…
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 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…
Chandra observations of SGR 1627-41 near quiescence
Hongjun An, Victoria M. Kaspi, John A. Tomsick +4
We report on an observation of SGR 1627-41 made with the Chandra X-ray Observatory on 2011 June 16. Approximately three years after its outburst activity in 2008, the source's flux…
Fermi-LAT constraints on the Pulsar Wind Nebula nature of HESS J1857+026
R. Rousseau, M. -H. Grondin, A. Van Etten +13
Since its launch, the Fermi satellite has firmly identified 5 pulsar wind nebulae plus a large number of candidates, all powered by young and energetic pulsars. HESS J1857+026 is a…
Discovery of the Optical/Ultraviolet/Gamma-ray Counterpart to the Eclipsing Millisecond Pulsar J1816+4510
D. L. Kaplan, K. Stovall, S. M. Ransom +21
The energetic, eclipsing millisecond pulsar J1816+4510 was recently discovered in a low-frequency radio survey with the Green Bank Telescope. With an orbital period of 8.7 hr and m…
