Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740
A. Noutsos, A. A. Abdo, M. Ackermann +146
We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
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…
Detecting massive gravitons using pulsar timing arrays
Kejia Lee, Fredrick A. Jenet, Richard H. Price +2
Massive gravitons are features of some alternatives to general relativity. This has motivated experiments and observations that, so far, have been consistent with the zero mass gra…
LOFAR, LEAP and beyond: Using next generation telescopes for pulsar astrophysics
Michael Kramer, Ben Stappers
Radio astronomy has benefited greatly from advances in technology and will continue to do so in the future. In fact, we are experiencing a revolution in the way radio astronomy is…
Early Pulsar Observations with LOFAR
Jason Hessels, Ben Stappers, Anastasia Alexov +10
This contribution to the proceedings of "A New Golden Age for Radio Astronomy" is simply intended to give some of the highlights from pulsar observations with LOFAR at the time of…
Relativistic spin-precession in binary pulsars
Michael Kramer
After the first prediction to expect geodetic precession in binary pulsars in 1974, made immediately after the discovery of a pulsar with a companion, the effects of relativistic s…
A Radio-loud Magnetar in X-ray Quiescence
Lina Levin, Matthew Bailes, Samuel Bates +12
As part of a survey for radio pulsars with the Parkes 64-m telescope we have discovered PSR J1622-4950, a pulsar with a 4.3-s rotation period. Follow-up observations show that the…
Switched magnetospheric regulation of pulsar spin-down
Andrew Lyne, George Hobbs, Michael Kramer +2
Pulsars are famed for their rotational clock-like stability and their highly-repeatable pulse shapes. However, it has long been known that there are unexplained deviations (often t…
Selection of radio pulsar candidates using artificial neural networks
R. P. Eatough, N. Molkenthin, M. Kramer +4
Radio pulsar surveys are producing many more pulsar candidates than can be inspected by human experts in a practical length of time. Here we present a technique to automatically id…
Long-term timing of four millisecond pulsars
G. H. Janssen, B. W. Stappers, C. G. Bassa +3
We have timed four millisecond pulses, PSRs J1721-2457, J1745-0952, J1810-2005, and J1918-0642, for up to a total of 10.5 years each using multiple telescopes in the European Pulsa…
Precision timing of PSR J1012+5307 and strong-field GR tests
Kosmas Lazaridis, Norbert Wex, Axel Jessner +10
We report on the high precision timing analysis of the pulsar-white dwarf binary PSR J1012+5307. Using 15 years of multi-telescope data from the European Pulsar Timing Array (EPTA)…
