Recent Globular Cluster Searches with Arecibo and the Green Bank Telescope
S. M. Ransom, J. W. T. Hessels, I. H. Stairs +4
We report the discovery of seven new millisecond pulsars during 20 cm searches of 19 globular clusters using the recently upgraded Arecibo Telescope and the new Green Bank Telescop…
The Massive Binary Pulsar J1740-3052
I. H. Stairs, R. N. Manchester, A. G. Lyne +4
The young pulsar J1740-3052 is in an 8-month orbit with a companion of at least 11 solar masses. We present multifrequency GBT and Parkes timing observations, and discuss implicati…
Magnetar-like X-ray Bursts from an Anomalous X-ray Pulsar
F. P. Gavriil, V. M. Kaspi, P. M. Woods
Anomalous X-ray Pulsars (AXPs) are a class of rare X-ray pulsars whose energy source has been perplexing for some 20 years. Unlike other, better understood X-ray pulsars, AXPs cann…
The Pulsar Wind Nebula in G11.2-0.3
Mallory S. E. Roberts, Cindy R. Tam, Victoria M. Kaspi +5
We present an X-ray and radio study of the wind nebula surrounding the central pulsar PSR J1811-1925 in the supernova remnant G11.2-0.3. Using high resolution data obtained with th…
A Very Large Glitch in PSR J1806-2125
G. Hobbs, A. G. Lyne, B. C. Joshi +7
PSR J1806-2125 is a pulsar discovered in the Parkes multibeam pulsar survey with a rotational period of 0.4s and a characteristic age of 65kyr. Between MJDs 51462 and 51894 this pu…
Spectral Components of the Radio Composite Supernova Remnant G11.2-0.3
Cindy Tam, Mallory S. E. Roberts, Victoria M. Kaspi
We present a high-resolution radio study of the supernova remnant (SNR) G11.2-0.3 using archival VLA data. Spectral tomography is performed to determine the properties of this comp…
Constraining the Birth Events of Neutron Stars
V. M. Kaspi, D. J. Helfand
The prescient remark by Baade and Zwicky that supernovae beget neutron stars did little to prepare us for the remarkable variety of observational manifestations such objects displa…
