Two clocks in the PSR J0737--3039 binary system and their implications for the system's origin and evolution
D. R. Lorimer, M. Burgay, P. C. C. Freire +8
As discussed elsewhere in these proceedings, the double pulsar system is a magnificent laboratory for gravitational physics and for studying pulsar magnetospheres. Here we consider…
New limits on the strong equivalence principle from two long-period circular-orbit binary pulsars
D. R. Lorimer, P. C. C. Freire
Following a brief review of the principles of the strong equivalence principle (SEP) and tests for its violation in the strong and weak gravitational field regimes, we present prel…
A 20-cm Survey for Pulsars in Globular Clusters using the GBT and Arecibo
Scott Ransom, Jason Hessels, Ingrid Stairs +3
We have been conducting deep searches at ~20 cm of >30 globular clusters (GCs) using the 305-m Arecibo telescope in Puerto Rico and the 100-m Green Bank telescope (GBT) in West Vir…
The PSR J0514-4002A binary system in NGC 1851
P. C. C. Freire, Y. Gupta, S. M. Ransom +1
Using the Giant Metrewave Radio Telescope (GMRT), we have discovered PSR J0514-4002A, a binary millisecond pulsar in the globular cluster NGC 1851. This pulsar has a rotational per…
A 20 cm Search for Pulsars in Globular Clusters with Arecibo and the GBT
Jason W. T. Hessels, Scott M. Ransom, Ingrid H. Stairs +4
We are conducting deep searches for radio pulsations at L-band (~ 20cm) towards more than 30 globular clusters using the 305m Arecibo telescope in Puerto Rico and the 100m Green Ba…
