A Deep Chandra Survey of the Globular Cluster 47 Tucanae: Catalog of Point Sources
C. O. Heinke, J. E. Grindlay, P. D. Edmonds +5
We have detected 300 X-ray sources within the half-mass radius (2.79') of the globular cluster 47 Tucanae in a deep (281 ks) Chandra exposure. We perform photometry and simple spec…
Long-term variations in the pulse emission from PSR J0737-3039B
M. Burgay, A. Possenti, R. N. Manchester +12
Analysis of 20 months of observations at the Parkes radio telescope shows secular changes in the pulsed emission from J0737-3039B, the 2.77 s pulsar of the double-pulsar system. Pu…
The Mean Pulse Profile of PSR J0737-3039A
R N Manchester, M Kramer, A Possenti +12
General relativity predicts that the spin axes of the pulsars in the double-pulsar system (PSR J0737-3039A/B) will precess rapidly, in general leading to a change in the observed p…
