Measurement and correction of variations in interstellar dispersion in high-precision pulsar timing
M. J. Keith, W. Coles, R. M. Shannon +16
Signals from radio pulsars show a wavelength-dependent delay due to dispersion in the interstellar plasma. At a typical observing wavelength, this delay can vary by tens of microse…
The Parkes Pulsar Timing Array Project
R. N. Manchester, G. Hobbs, M. Bailes +28
A "pulsar timing array" (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of "global" phenomena such a…
Does a 'stochastic' background of gravitational waves exist in the pulsar timing band?
V. Ravi, J. S. B. Wyithe, G. Hobbs +4
We investigate the effects of gravitational waves (GWs) from a simulated population of binary super-massive black holes (SMBHs) on pulsar timing array datasets. We construct a dist…
Development of a pulsar-based timescale
G. Hobbs, W. Coles, R. N. Manchester +21
Using observations of pulsars from the Parkes Pulsar Timing Array (PPTA) project we develop the first pulsar-based timescale that has a precision comparable to the uncertainties in…
Constraining the coalescence rate of supermassive black-hole binaries using pulsar timing
Z. L. Wen, F. A. Jenet, D. Yardley +2
Pulsar timing observations are used to place constraints on the rate of coalescence of supermassive black-hole (SMBH) binaries as a function of mass and redshift. In contrast to th…
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…
