Chandra X-ray Detection of the High-Magnetic-Field Radio Pulsar PSR J1718-3718
V. M. Kaspi, M. A. McLaughlin
We report on the serendipitous X-ray detection, using the Chandra X-ray Observatory, of the radio pulsar J1718-3718. This pulsar has one of the highest inferred surface dipole magn…
The Millisecond Pulsars in NGC 6760
Paulo C. C. Freire, Jason W. T. Hessels, David J. Nice +3
We present the results of recent Arecibo and Green Bank observations of the globular cluster NGC 6760. Using Arecibo, a phase-coherent timing solution has been obtained for the pre…
Large-scale magnetic fields from density perturbations
S. Matarrese, S. Mollerach, A. Notari +1
We derive the minimal seed magnetic field which unavoidably arises in the radiation and matter eras, prior to recombination, by the rotational velocity of ions and electrons, gravi…
Correlated Infrared and X-ray Flux Changes Following the 2002 June Outburst of the Anomalous X-ray Pulsar 1E 2259+586
C. R. Tam, V. M. Kaspi, M. H. van Kerkwijk +1
We present the results of a near-infrared monitoring program of the Anomalous X-ray Pulsar 1E 2259+586, performed at the Gemini Observatory. This program began three days after the…
21 years of Timing PSR B1509-58
Margaret A. Livingstone, Victoria M. Kaspi, Fotis P. Gavriil +1
We present an updated timing solution for the young, energetic pulsar PSR B1509-58 based on 21.3 years of radio timing data and 7.6 years of X-ray timing data. No glitches have occ…
Near-infrared identification of the counterpart to X1908+075: a new OB-supergiant X-ray binary
Thierry Morel, Yves Grosdidier
We report the near-infrared (IR) identification of the likely counterpart to X1908+075, a highly-absorbed Galactic X-ray source recently suspected to belong to the rare class of OB…
