The MeerKAT Pulsar Timing Array: Maps of the gravitational-wave sky with the 4.5 year data release

Kathrin Grunthal, Rowina S. Nathan, Eric Thrane +16

In an accompanying publication, the MeerKAT Pulsar Timing Array (MPTA) collaboration reports tentative evidence for the presence of a stochastic gravitational-wave background, foll…

The MeerKAT Pulsar Timing Array: The first search for gravitational waves with the MeerKAT radio telescope

Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +22

Pulsar Timing Arrays search for nanohertz-frequency gravitational waves by regularly observing ensembles of millisecond pulsars over many years to look for correlated timing residu…

The MeerKAT Pulsar Timing Array: The -year data release and the noise and stochastic signals of the millisecond pulsar population

Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +21

Pulsar timing arrays are ensembles of regularly observed millisecond pulsars timed to high precision. Each pulsar in an array could be affected by a suite of noise processes, most…

Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

The gravitational-wave background null hypothesis: Characterizing noise in millisecond pulsar arrival times with the Parkes Pulsar Timing Array

Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +19

The noise in millisecond pulsar (MSP) timing data can include contributions from observing instruments, the interstellar medium, the solar wind, solar system ephemeris errors, and…

Search for an isotropic gravitational-wave background with the Parkes Pulsar Timing Array

Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +26

Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common t…

The Parkes Pulsar Timing Array Third Data Release

Andrew Zic, Daniel J. Reardon, Agastya Kapur +31

We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The release contains observations of 32 pulsars obtained using the 64-m Parkes "Murriyang" rad…

Missed opportunities: GRB 211211A and the case for continual gravitational-wave coverage with a single observatory

Nikhil Sarin, Paul D. Lasky, Rowina S. Nathan

Gamma-ray burst GRB 211211A may have been the result of a neutron star merger at Mpc. However, none of the LIGO-Virgo detectors were operating at the time. We show tha…

Flickering of the Vela pulsar during its 2016 glitch

Gregory Ashton, Paul D. Lasky, Rowina Nathan +1

The first pulse-to-pulse observations of a neutron star glitch in the Vela pulsar identified a null pulse hinting at the sudden disruption of the neutron star's magnetosphere. The…

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…
