An emission state switching radio transient with a 54 minute period
M. Caleb, E. Lenc, D. L. Kaplan +19
Long-period radio transients are an emerging class of extreme astrophysical events of which only three are known. These objects emit highly polarised, coherent pulses of typically…
Radio observations of two intermittent pulsars: PSRs J1832+0029 and J1841-0500
S. Q. Wang, J. B. Wang, G. Hobbs +8
We present long-term observations of two intermittent pulsars, PSRs~J1832+0029 and J18410500 using the Parkes 64\,m radio telescope. The radio emission for these pulsars switche…
Commensal discovery of four Fast Radio Bursts during Parkes Pulsar Timing Array observations
S. Osłowski, R. M. Shannon, V. Ravi +25
The Parkes Pulsar Timing Array (PPTA) project monitors two dozen millisecond pulsars (MSPs) in order to undertake a variety of fundamental physics experiments using the Parkes 64m…
Comparison of Pulsar Positions from Timing and Very Long Baseline Astrometry
J. B. Wang, W. A. Coles, G. Hobbs +22
Pulsar positions can be measured with high precision using both pulsar timing methods and very-long-baseline interferometry (VLBI). Pulsar timing positions are referenced to a sola…
Timing analysis for 20 millisecond pulsars in the Parkes Pulsar Timing Array
D. J. Reardon, G. Hobbs, W. Coles +18
We present timing models for 20 millisecond pulsars in the Parkes Pulsar Timing Array. The precision of the parameter measurements in these models has been improved over earlier re…
Detection of 107 glitches in 36 southern pulsars
M. Yu, R. N. Manchester, G. Hobbs +9
Timing observations from the Parkes 64-m radio telescope for 165 pulsars between 1990 and 2011 have been searched for period glitches. A total of 107 glitches were identified in 36…
Wide radio beams from gamma-ray pulsars
V. Ravi, R. N. Manchester, G. Hobbs
We investigate the radio and gamma-ray beaming properties of normal and millisecond pulsars by selecting two samples from the known populations. The first, Sample G, contains pulsa…
