The Parkes Pulsar Timing Array
R. N. Manchester
Detection and study of gravitational waves from astrophysical sources is a major goal of current astrophysics. Ground-based laser-interferometer systems such as LIGO and VIRGO are…
Dispersion Measure Variations and their Effect on Precision Pulsar Timing
X. P. You, G. Hobbs, W. A. Coles +11
We present an analysis of the variations seen in the dispersion measures (DMs) of 20 millisecond pulsars observed as part of the Parkes Pulsar Timing Array project. We carry out a…
New Phase-coherent Measurements of Pulsar Braking Indices
Margaret A. Livingstone, Victoria M. Kaspi, Fotis P. Gavriil +3
Pulsar braking indices offer insight into the physics that underlies pulsar spin-down. Only five braking indices have been measured via phase-coherent timing; all measured values a…
The Highly Relativistic Binary Pulsar PSR J0737-3039A: Discovery and Implications
M. Burgay, N. D'Amico, A. Possenti +10
PSR J0737-3039A is a millisecond pulsar with a spin period of 22.7 ms included in a double-neutron star system with an orbital period of 2.4 hrs. Its companion has also been detect…
The double pulsar -- A new testbed for relativistic gravity
M. Kramer, A. G. Lyne, M. Burgay +9
The first ever double pulsar, discovered by our team a few months ago, consists of two pulsars, one with period of 22 ms and the other with a period of 2.7 s. This binary system wi…
PSRCHIVE and PSRFITS An Open Approach to Radio Pulsar Data Storage and Analysis
A. W. Hotan, W. van Straten, R. N. Manchester
A new set of software applications and libraries for use in the archival and analysis of pulsar astronomical data is introduced. Known collectively as the PSRCHIVE scheme, the code…
