Accounting for detector calibration uncertainty in black-hole ringdown analysis
Rowina S. Nathan, Shingo Hido, Neil Lu +3
Detector calibration systematics can bias measurements of a remnant black hole's mass and spin, producing spurious evidence against general relativity if unaccounted for. The ringd…
From driven oscillations to free ringdown: a particle plunging into Kerr
Colin Weller, Andrew Laeuger, Fulin Li +5
We show that a ringdown waveform can admit a constant-coefficient quasinormal-mode (QNM) representation while its individual QNM-pole contributions remain driven. To establish this…
Optimising gravitational-wave sky maps for pulsar timing arrays
Kathrin Grunthal, David J. Champion, Eric Thrane +3
Pulsar timing arrays (PTAs) have recently reported compelling evidence for the presence of a gravitational-wave background signal. Mapping the gravitational-wave background is key…
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…
Transdimensional inference for gravitational-wave astronomy with Bilby
Hui Tong, Nir Guttman, Teagan A. Clarke +8
It has become increasingly useful to answer questions in gravitational-wave astronomy using transdimensional models where the number of free parameters can be varied depending on t…
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…
Improving pulsar-timing solutions through dynamic pulse fitting
Rowina S. Nathan, Matthew T. Miles, Gregory Ashton +5
Precision pulsar timing is integral to the detection of the nanohertz stochastic gravitational-wave background as well as understanding the physics of neutron stars. Conventional p…
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…
