First detection of frequency-dependent, time-variable dispersion measures
J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +11
Context. High-precision pulsar-timing experiments are affected by temporal variations of the Dispersion Measure (DM), which are related to spatial variations in the interstellar el…
A Study of Multi-frequency Polarization Pulse Profiles of Millisecond Pulsars
S. Dai, G. Hobbs, R. N. Manchester +23
We present high signal-to-noise ratio, multi-frequency polarization pulse profiles for 24 millisecond pulsars that are being observed as part of the Parkes Pulsar Timing Array (PPT…
Searching for gravitational wave memory bursts with the Parkes Pulsar Timing Array
J. B. Wang, G. Hobbs, W. Coles +17
Anisotropic bursts of gravitational radiation produced by events such as super-massive black hole mergers leave permanent imprints on space. Such gravitational wave "memory" (GWM)…
An all-sky search for continuous gravitational waves in the Parkes Pulsar Timing Array data set
X. -J. Zhu, G. Hobbs, L. Wen +16
We present results of an all-sky search in the Parkes Pulsar Timing Array (PPTA) Data Release 1 data set for continuous gravitational waves (GWs) in the frequency range from $5\tim…
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…
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…
