The international pulsar timing array project: using pulsars as a gravitational wave detector
G. Hobbs, A. Archibald, Z. Arzoumanian +55
The International Pulsar Timing Array project combines observations of pulsars from both Northern and Southern hemisphere observatories with the main aim of detecting ultra-low fre…
Rotational asymmetry of pulsar profiles
J. Dyks, G. A. E. Wright, P. Demorest
We analyse the influence of rotation on shapes of pulse profiles of fast-rotating (millisecond) pulsars. Corotation has two opposing effects: 1) the caustic enhancement of the trai…
Radio detection of LAT PSRs J1741-2054 and J2032+4127: no longer just gamma-ray pulsars
F. Camilo, P. S. Ray, S. M. Ransom +24
Sixteen pulsars have been discovered so far in blind searches of photons collected with the Large Area Telescope on the Fermi Gamma-ray Space Telescope. We here report the discover…
The nature of pulsar radio emission
J. Dyks, B. Rudak, P. Demorest
High-quality averaged radio profiles of some pulsars exhibit double, highly symmetric features both in emission and absorption. It is shown that both types of features are produced…
Pulsed Gamma-rays from PSR J2021+3651 with the Fermi Large Area Telescope
A. A. Abdo
We report the detection of pulsed gamma-rays from the young, spin-powered radio pulsar PSR J2021+3651 using data acquired with the Large Area Telescope (LAT) on the Fermi Gamma-ray…
Gravitational Wave Astronomy Using Pulsars: Massive Black Hole Mergers & the Early Universe
P. Demorest, J. Lazio, A. Lommen
Gravitational waves (GWs) are fluctuations in the fabric of spacetime predicted by Einstein's theory of general relativity. Using a collection of millisecond pulsars as high-precis…
