Spitzer Mid-infrared Upper Limits on Anomalous X-Ray Pulsars 1E 1048.1-5937, 1RXS J170849-400910, and XTE J1810-197
Z. Wang, V. M. Kaspi, S. J. U. Higdon
We report on mid-infrared imaging observations of the anomalous X-ray pulsars (AXPs) 1E 1048.1-5937, 1RXS J170849-400910, and XTE J1810-197. The observations were carried out at 4.…
10 Years of RXTE Monitoring of Anomalous X-ray Pulsar 4U 0142+61: Long-Term Variability
Rim Dib, Victoria M. Kaspi, Fotis P. Gavriil
We report on 10 yr of monitoring of the 8.7-s Anomalous X-ray Pulsar 4U 0142+61 using the Rossi X-Ray Timing Explorer (RXTE). This pulsar exhibited stable rotation from 2000 until…
Chandra and XMM-Newton Observations of the Vela-like Pulsar B1046-58
M. E. Gonzalez, V. M. Kaspi, M. J. Pivovaroff +1
We present results from Chandra and XMM-Newton observations of the radio pulsar B1046-58. A high-resolution spatial analysis reveals an asymmetric pulsar wind nebula (PWN) ~6"x11"…
PSR J1119-6127 and the X-ray Emission from High Magnetic Field Radio Pulsars
M. E. Gonzalez, V. M. Kaspi, F. Camilo +2
The existence of radio pulsars having inferred magnetic fields in the magnetar regime suggests that possible transition objects could be found in the radio pulsar population. The d…
Recent Progress on Anomalous X-ray Pulsars
V. M. Kaspi
I review recent observational progress on Anomalous X-ray Pulsars, with an emphasis on timing, variability, and spectra. Highlighted results include the recent timing and flux stab…
Chandra Monitoring of the Candidate Anomalous X-ray Pulsar AX J1845.0-0258
C. R. Tam, V. M. Kaspi, B. M. Gaensler +1
The population of clearly identified anomalous X-ray pulsars has recently grown to seven, however, one candidate anomalous X-ray pulsar (AXP) still eludes re-confirmation. Here, we…
A Survey of 56 Mid-latitude EGRET Error Boxes for Radio Pulsars
F. Crawford, M. S. E. Roberts, J. W. T. Hessels +4
We have conducted a radio pulsar survey of 56 unidentified gamma-ray sources from the 3rd EGRET catalog which are at intermediate Galactic latitudes (5 deg. < |b| < 73 deg.). For e…
Discovery of 14 radio pulsars in a survey of the Magellanic Clouds
R N Manchester, G Fan, A G Lyne +1
A systematic survey of the Large and Small Magellanic Clouds for radio pulsars using the Parkes radio telescope and the 20-cm multibeam receiver has resulted in the discovery of 14…
Arecibo and the ALFA Pulsar Survey
J. van Leeuwen, J. M. Cordes, D. R. Lorimer +34
The recently started Arecibo L-band Feed Array (ALFA) pulsar survey aims to find ~1000 new pulsars. Due to its high time and frequency resolution the survey is especially sensitive…
A Radio Pulsar Spinning at 716 Hz
Jason W. T. Hessels, Scott M. Ransom, Ingrid H. Stairs +3
We have discovered a 716-Hz eclipsing binary radio pulsar in the globular cluster Terzan 5 using the Green Bank Telescope. It is the fastest-spinning neutron star ever found, break…
A Braking Index for the Young, High-Magnetic-Field, Rotation-Powered Pulsar in Kes 75
Margaret A. Livingstone, Victoria M. Kaspi, E. V. Gotthelf +1
We present the first phase-coherent measurement of a braking index for the young, energetic rotation-powered pulsar PSR J1846-0258. This 324 ms pulsar is located at the center of t…
