Tests of general relativity from timing the double pulsar

M. Kramer, I. H. Stairs, R. N. Manchester +12

The double pulsar system, PSR J0737-3039A/B, is unique in that both neutron stars are detectable as radio pulsars. This, combined with significantly higher mean orbital velocities…

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…

Chandra X-Ray Observations of Nineteen Millisecond Pulsars in the Globular Cluster 47 Tucanae

Slavko Bogdanov, Jonathan E. Grindlay, Craig O. Heinke +3

We present spectral and long-timescale variability analyses of \textit{Chandra} ACIS-S observations of the 19 millisecond pulsars (MSPs) with precisely known positions in the globu…

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…
