Pulsar Timing with the Parkes Radio Telescope for the Fermi Mission (2009)

Weltevrede, P., Johnston, S., Manchester, R. N., Bhat, R., Burgay, M., Champion, D., ...

We report here on two years of timing of 168 pulsars using the Parkes radio telescope. The vast majority of these pulsars have spin-down luminosities in excess of 10^34 erg/s and are prime target...

Searches for gravitational waves from known pulsars with S5 LIGO data (2009)

Collaboration, The LIGO Scientific, Abbott, R., Acernese, F., Adhikari, R., Ajith, P., ...

We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search ephemerides overlapping the run...

Timing stability of millisecond pulsars and prospects for gravitational-wave detection (2009)

Verbiest, J. P. W., Bailes, M., Coles, W. A., Hobbs, G. B., Van Straten, W., Champion, D. J., ...

Analysis of high-precision timing observations of an array of approx. 20 millisecond pulsars (a so-called ''timing array'') may ultimately result in the detection of a stochastic gravitational-wave...

Gravitational wave detection using pulsars: status of the Parkes Pulsar Timing Array project (2008)

Hobbs, G. B., Bailes, M., Bhat, N. D. R., Burke-Spolaor, S., Champion, D. J., Coles, W., ...

The first direct detection of gravitational waves may be made through observations of pulsars. The principal aim of pulsar timing array projects being carried out worldwide is to detect ultra-low...

Pulsar Timing for the Fermi Gamma-ray Space Telescope (2008)

Smith, D. A., Guillemot, L., Camilo, F., Cognard, I., Dumora, D., Espinoza, C., ...

We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of pulsars in gamma...

Precision timing of PSR J0437-4715 : an accurate pulsar distance, a high pulsar mass, and a limit on the variation of Newton's gravitational constant (2008)

Verbiest, J. P. W., Bailes, M., Van Straten, W., Hobbs, G. B., Edwards, R. T., Manchester, R. N., ...

Analysis of 10 years of high-precision timing data on the millisecond pulsar PSR J0437–4715 has resulted in a model-independent kinematic distance based on an apparent orbital period derivative,...

Precision timing of PSR J0437-4715: an accurate pulsar distance, a high pulsar mass and a limit on the variation of Newton's gravitational constant (2008)

Verbiest, J. P. W., Bailes, M., Van Straten, W., Hobbs, G. B., Edwards, R. T., Manchester, R. N., ...

Analysis of ten years of high-precision timing data on the millisecond pulsar PSR J0437-4715 has resulted in a model-independent kinematic distance based on an apparent orbital period derivative,...

An improved solar wind electron-density model for pulsar timing (2007)

You, X. P., Hobbs, G. B., Coles, W. A., Manchester, R. N., Han, J. L.

Variations in the solar wind density introduce variable delays into pulsar timing observations. Current pulsar timing analysis programs only implement simple models of the solar wind, which not only...

Dispersion measure variations and their effect on precision pulsar timing (2007)
