The Thousand-Pulsar-Array programme on MeerKAT II: observing strategy for pulsar monitoring with subarrays
X. Song, P. Weltevrede, M. J. Keith +15
The Thousand Pulsar Array (TPA) project currently monitors about 500 pulsars with the sensitive MeerKAT radio telescope by using subarrays to observe multiple sources simultaneousl…
The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
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…
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 Thousand-Pulsar-Array programme on MeerKAT IV: Polarisation properties of young, energetic pulsars
M. Serylak, S. Johnston, M. Kramer +16
We present observations of 35 high spin-down energy radio pulsars using the MeerKAT telescope. Polarisation profiles and associated parameters are also presented. We derive the geo…
Precision orbital dynamics from interstellar scintillation arcs for PSR J0437-4715
Daniel J. Reardon, William A. Coles, Matthew Bailes +17
Intensity scintillations of radio pulsars are known to originate from interference between waves scattered by the electron density irregularities of interstellar plasma, often lead…
