Pulsars with the Australian Square Kilometre Array Pathfinder
I. H. Stairs, M. J. Keith, Z. Arzoumanian +33
The Australian Square Kilometre Array Pathfinder (ASKAP) is a 36-element array with a 30-square-degree field of view being built at the proposed SKA site in Western Australia. We a…
Three Millisecond Pulsars in FERMI LAT Unassociated Bright Sources
S. M. Ransom, P. S. Ray, F. Camilo +33
We searched for radio pulsars in 25 of the non-variable, unassociated sources in the Fermi LAT Bright Source List with the Green Bank Telescope at 820 MHz. We report the discovery…
On the nature and evolution of the unique binary pulsar J1903+0327
P. C. C. Freire, C. G. Bassa, N. Wex +16
(abridged) PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-day orbit with a (~ 1Msun) companion poses a challenge to our understanding of stellar evolution in bi…
Precise Gamma-Ray Timing and Radio Observations of 17 Fermi Gamma-Ray Pulsars
P. S. Ray, M. Kerr, D. Parent +23
We present precise phase-connected pulse timing solutions for 16 gamma-ray-selected pulsars recently discovered using the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Te…
The Massive Pulsar PSR J1614-2230: Linking Quantum Chromodynamics, Gamma-ray Bursts, and Gravitational Wave Astronomy
Feryal Ozel, Dimitrios Psaltis, Scott Ransom +2
The recent measurement of the Shapiro delay in the radio pulsar PSR J1614-2230 yielded a mass of 1.97 +/- 0.04 M_sun, making it the most massive pulsar known to date. Its mass is h…
Shapiro delay measurement of a two solar mass neutron star
Paul Demorest, Tim Pennucci, Scott Ransom +2
Neutron stars are composed of the densest form of matter known to exist in our universe, and thus provide a unique laboratory for exploring the properties of cold matter at super-n…
