Timing of young radio pulsars – I. Timing noise, periodic modulation, and proper motion [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
The smooth spin-down of young pulsars is perturbed by two non-deterministic phenomenon, glitches, and timing noise. Although the timing noise provides insights into nuclear and plasma physics at extreme densities, it acts as a barrier to high-precision

On the beam properties of radio pulsars with interpulse emission [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
In the canonical picture of pulsars, radio emission arises from a narrow cone centred on the star’s magnetic axis but many basic details remain unclear.

On the Spectral Shape of Non-recycled γ-ray Pulsars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
More than 100 γ−ray pulsars have been discovered by the Fermi Gamma-ray Space Telescope. With a significantly enlarged sample size, it is possible to compare the properties of different classes. Radio-quiet (RQ) γ−ray pulsars form a distinct population,

Searching a Thousand Radio Pulsars for Gamma-Ray Emission [PDF]

open access: yesAstrophysical Journal, 2018
Identifying as many gamma-ray pulsars as possible in the Fermi Large Area Telescope (LAT) data helps test pulsar emission models by comparing predicted and observed properties for a large, varied sample with as little selection bias as possible.

Robust limits on photon mass from statistical samples of extragalactic radio pulsars [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2018
The photon zero-mass hypothesis has been investigated for a long time using the frequency-dependent time delays of radio emissions from astrophysical sources.

Gravity experiments with radio pulsars [PDF]

open access: yesLiving Reviews in Relativity
The discovery of the first pulsar in a binary star system, the Hulse–Taylor pulsar, 50 years ago opened up an entirely new field of experimental gravity.

Evidence for magnetospheric effects on the radiation of radio pulsars [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We have conducted the largest investigation to date into the origin of phase resolved, apparent RM variations in the polarized signals of radio pulsars.

Spectral properties of 441 radio pulsars [PDF]

open access: yes, 2017
We present a study of the spectral properties of 441 pulsars observed with the Parkes radio telescope near the centre frequencies of 728, 1382 and 3100 MHz.

Markov Chain Monte Carlo population synthesis of single radio pulsars in the Galaxy [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We present a model of evolution of solitary neutron stars, including spin parameters, magnetic field decay, motion in the Galactic potential, and birth inside spiral arms.

Are radio pulsars strange stars ? [PDF]

open access: yesAstronomy & Astrophysics, 2001
A remarkably precise observational relation for pulse core component widths of radio pulsars is used to derive stringent limits on pulsar radii, strongly indicating that pulsars are strange stars rather than neutron stars. This is achieved by inclusion of general relativistic effects due to the pulsar mass on the size of the emission region needed to ...
