Pulsar Timing with the Parkes Radio Telescope for the Fermi Mission

TL;DR

This paper presents two years of pulsar timing data from the Parkes telescope, providing ephemerides for gamma-ray detected pulsars and reporting new glitch parameters, aiding Fermi gamma-ray studies.

Contribution

It offers new timing ephemerides for pulsars detected by Fermi and reports previously unknown glitch events, supporting gamma-ray pulsar research.

Findings

Timing ephemerides for 10 Fermi-detected pulsars

Parameters for 14 glitches in 13 pulsars

Seven pulsars with newly identified glitches

Abstract

We report here on two years of timing of 168 pulsars using the Parkes radio telescope. The vast majority of these pulsars have spin-down luminosities in excess of 10^34 erg/s and are prime target candidates to be detected in gamma-rays by the Fermi Gamma-Ray Space Telescope. We provide the ephemerides for the ten pulsars being timed at Parkes which have been detected by Fermi in its first year of operation. These ephemerides, in conjunction with the publicly available photon list, can be used to generate gamma-ray profiles from the Fermi archive. We will make the ephemerides of any pulsars of interest available to the community upon request. In addition to the timing ephemerides, we present the parameters for 14 glitches which have occurred in 13 pulsars, seven of which have no previously known glitch history. The Parkes timing programme, in conjunction with Fermi observations, is expected to continue for at least the next four years.
