Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
D. R. Madison, X. -J. Zhu, G. Hobbs +23
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
A Study of Multi-frequency Polarization Pulse Profiles of Millisecond Pulsars
S. Dai, G. Hobbs, R. N. Manchester +23
We present high signal-to-noise ratio, multi-frequency polarization pulse profiles for 24 millisecond pulsars that are being observed as part of the Parkes Pulsar Timing Array (PPT…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
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…
From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release
L. Lentati, R. M. Shannon, W. A. Coles +80
We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…
Commensal discovery of four Fast Radio Bursts during Parkes Pulsar Timing Array observations
S. OsÅowski, 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…
Pulsar Observations of Extreme Scattering Events
W. A. Coles, M. Kerr, R. M. Shannon +17
Extreme scattering events (ESEs) in the interstellar medium (ISM) were first observed in regular flux measurements of compact extragalactic sources. They are characterized by a flu…
The International Pulsar Timing Array: First Data Release
J. P. W. Verbiest, L. Lentati, G. Hobbs +89
The highly stable spin of neutron stars can be exploited for a variety of (astro-)physical investigations. In particular arrays of pulsars with rotational periods of the order of m…
