The double pulsar system J0737 – 3039 – a 22.7 ms pulsar in a compact 2.4 hr orbit about a 2.7 s pulsar was one of the long-awaited "holy grails" of pulsar astronomy. After only two years of timing, the system is close to surpassing the original Hulse-Taylor binary as a test of general relativity. On-going timing should soon reveal second-order effects in the post-Newtonian parameters. In addition, the observed interactions of the radio beams of the two pulsars provide a unique laboratory for…

N ov 2 00 8 Binary and Millisecond Pulsars
We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to
Cosmic neutron-star merger rate and gravitational waves constrained by the r-process nucleosynthesis
The cosmic evolution of the neutron-star merger (NSM) rate can be deduced from the observed cosmic star formation rate. This allows us to estimate the rate expected in the horizon of the

We have analyzed single pulses from PSR J0737-3039B, the 2.8 s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz. We report
The Parkes Multibeam Pulsar Survey: PSR J1811-1736, a Pulsar in a Highly Eccentric Binary System
We are undertaking a high-frequency survey of the Galactic plane for radio pulsars, using the 13-element multibeam receiver on the 64-m Parkes radio telescope. We describe briefly the survey system
PSR J1518+4904: A mildly relativistic binary pulsar system
PSR J1518+4904 is a recently discovered 40.9 ms pulsar in an 8.6 day, moderately eccentric orbit. We have measured pulse arrival times for this pulsar over 1.4 yr at several radio frequencies, from
PSR J1756?2251: A New Relativistic Double Neutron Star System
We report the discovery during the Parkes Multibeam Pulsar Survey of PSR J1756-2251, a 28.5 ms pulsar in a relativistic binary system. Subsequent timing observations showed the pulsar to have an
PSR J1829+2456: a relativistic binary pulsar
We report the discovery of a new binary pulsar, PSR J1829+2456, found during a midlatitude drift-scan survey with the Arecibo telescope. Our initial timing observations show the 41-ms pulsar to be in
