High signal-to-noise ratio observations and the ultimate limits of precision pulsar timing
Stefan Oslowski, Willem van Straten, George Hobbs +2
We demonstrate that the sensitivity of high-precision pulsar timing experiments will be ultimately limited by the broadband intensity modulation that is intrinsic to the pulsar's s…
Rotation measure variations for 20 millisecond pulsars
Wenming Yan, R. N. Manchester, Willem van Straten +14
We report on variations in the mean position angle of the 20 millisecond pulsars being observed as part of the Parkes Pulsar Timing Array (PPTA) project. It is found that the obser…
Polarization observations of 20 millisecond pulsars
Wenming Yan, R. N. Manchester, Willem van Straten +14
Polarization profiles are presented for 20 millisecond pulsars that are being observed as part of the Parkes Pulsar Timing Array project. The observations used the Parkes multibeam…
On detection of the stochastic gravitational-wave background using the Parkes pulsar timing array
D. R. B. Yardley, W. A. Coles, G. B. Hobbs +12
We search for the signature of an isotropic stochastic gravitational-wave background in pulsar timing observations using a frequency-domain correlation technique. These observation…
