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…
Constraining inflation with nonminimal derivative coupling with the Parkes Pulsar Timing Array third data release
Chang Han, Li-Yang Chen, Zu-Cheng Chen +13
We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally…
Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
Bow Shock and Local Bubble Plasma Unveiled by the Scintillating Millisecond Pulsar J04374715
Daniel J. Reardon, Robert Main, Stella Koch Ocker +10
The ionized interstellar medium contains au-scale (and below) structures that scatter radio waves from pulsars, resulting in scintillation. Power spectral analysis of scintillation…
The neutron star mass, distance, and inclination from precision timing of the brilliant millisecond pulsar J04374715
Daniel J. Reardon, Matthew Bailes, Ryan M. Shannon +17
The observation of neutron stars enables the otherwise impossible study of fundamental physical processes. The timing of binary radio pulsars is particularly powerful, as it enable…
MeerKAT Pulsar Timing Array parallaxes and proper motions
Mohsen Shamohammadi, Matthew Bailes, Christopher Flynn +10
We have determined positions, proper motions, and parallaxes of millisecond pulsars (MSPs) from years of MeerKAT radio telescope observations. Our timing and noise ana…
