The double pulsar: evolutionary constraints from the system geometry
R. D. Ferdman, I. H. Stairs, M. Kramer +6
The double pulsar system PSR J0737-3039A/B is a highly relativistic double neutron star (DNS) binary, with a 2.4-hour orbital period. The low mass of the second-formed NS, as well…
A 610-MHz Galactic Plane Pulsar Search with the Giant Meterwave Radio Telescope
B. C. Joshi, M. A. McLaughlin, M. Kramer +5
We report on the discovery of three new pulsars in the first blind survey of the north Galactic plane (45 < l < 135 ; |b| < 1) with the Giant Meterwave Radio telescope (GMRT) at an…
Discovery of Pulsations and a Possible Spectral Feature in the X-ray Emission from Rotating Radio Transient J1819-1458
M. A. McLaughlin, N. Rea, B. M. Gaensler +7
PSR J1819-1458 is a rotating radio transient (RRAT) source with an inferred surface dipole magnetic field strength of 5e13 G and a 4.26-s spin period. We present XMM-Newton observa…
A characteristic observable signature of preferred frame effects in relativistic binary pulsars
N. Wex, M. Kramer
In this paper we develop a consistent, phenomenological methodology to measure preferred-frame effects (PFEs) in binary pulsars that exhibit a high rate of periastron advance. We s…
Age constraints in the double pulsar system J0737-3039
D. R. Lorimer, P. C. C. Freire, I. H. Stairs +10
We investigate the age constraints that can be placed on the double pulsar system using models for the spin-down of the first-born 22.7-ms pulsar A and the 2.77-s pulsar B with cha…
Upper limits on gravitational wave emission from 78 radio pulsars
The LIGO Scientific Collaboration, B. Abbott, M. Kramer +1
We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO600 gravitational wave dete…
LOFAR: A powerful tool for pulsar studies
B. W. Stappers, A. G. J. van Leeuwen, M. Kramer +2
The LOw Frequency ARray, LOFAR, will have the sensitivity, bandwidth, frequency range and processing power to revolutionise low-frequency pulsar studies. We present results of simu…
