The young, highly relativistic binary pulsar J1906+0746
D. R. Lorimer, I. H. Stairs, P. C. C. Freire +33
We report the discovery of PSR J1906+0746, a young 144-ms pulsar in a highly relativistic 3.98-hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence ti…
Arecibo Pulsar Survey Using ALFA. I. Survey Strategy and First Discoveries
J. M. Cordes, P. C. C. Freire, D. R. Lorimer +21
We report results from the initial stage of a long-term pulsar survey of the Galactic plane using the Arecibo L-band Feed Array (ALFA), a seven-beam receiver operating at 1.4 GHz w…
High-speed, multi-colour optical photometry of the anomalous X-ray pulsar 4U 0142+61 with ULTRACAM
V. S. Dhillon, T. R. Marsh, F. Hulleman +5
We present high-speed, multi-colour optical photometry of the anomalous X-ray pulsar 4U 0142+61, obtained with ULTRACAM on the 4.2-m William Herschel Telescope. We detect 4U 0142+6…
Long-term Phase-coherent X-ray Timing of PSR B0540-69
Margaret A. Livingstone, Victoria M. Kaspi, Fotis P. Gavriil
We present a new phase-coherent timing analysis for the young, energetic pulsar PSR B0540-69 using 7.6 yr of data from the Rossi X-Ray Timing Explorer. We measure the braking index…
A Burst and Simultaneous Short-Term Pulsed Flux Enhancement from the Magnetar Candidate 1E 1048.1-5937
Fotis P. Gavriil, Victoria M. Kaspi, Peter M. Woods
We report on the 2004 June 29 burst detected from the direction of the Anomalous X-ray Pulsar (AXP) 1E 1048.1-5937 using the Rossi X-ray Timing Explorer (RXTE). We find a simultane…
X-ray Bursts from the Transient Magnetar Candidate XTE J1810-197
P. M. Woods, C. Kouveliotou, F. P. Gavriil +6
We have discovered four X-ray bursts, recorded with the Rossi X-ray Timing Explorer Proportional Counter Array between 2003 September and 2004 April, that we show to originate from…
