Flux density variability of 286 radio pulsars from a decade of monitoring
H. Kumamoto, S. Dai, S. Johnston +7
The Parkes telescope has been monitoring 286 radio pulsars approximately monthly since 2007 at an observing frequency of 1.4 GHz. The wide dispersion measure (DM) range of the puls…
Wideband Monitoring Observations of PSR J1803-3002A in the Globular Cluster NGC 6522
Lei Zhang, Richard N. Manchester, Andrew D. Cameron +10
We report the first wideband monitoring observations of PSR J1803-3002A, a relatively bright millisecond pulsar in the globular cluster NGC 6522 with a spin period of 7.1 ms and no…
Searching for gravitational wave bursts from cosmic string cusps with the Parkes Pulsar Timing Array
N. Yonemaru, S. Kuroyanagi, G. Hobbs +12
Cosmic strings are potential gravitational wave (GW) sources that can be probed by pulsar timing arrays (PTAs). In this work we develop a detection algorithm for a GW burst from a…
Understanding and improving the timing of PSR J0737-3039B
Aristeidis Noutsos, G. Desvignes, M. Kramer +11
The double pulsar (PSR J0737-3039A/B) provides some of the most stringent tests of general relativity (GR) and its alternatives. The success of this system in tests of GR is largel…
Identifying and mitigating noise sources in precision pulsar timing data sets
Boris Goncharov, D. J. Reardon, R. M. Shannon +14
Pulsar timing array projects measure the pulse arrival times of millisecond pulsars for the primary purpose of detecting nanohertz-frequency gravitational waves. The measurements i…
The two emission states of PSR B1534+12
S. Q. Wang, G. Hobbs, J. B. Wang +10
We have observed PSR~B1534+12 (J1537+1155), a pulsar with a neutron star companion, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We found that this pulsa…
