Probing turbulence in the ionized interstellar medium using young pulsars. I. Dispersion measure variations
S. J. I. Melfor, A. Parthasarathy, S. Johnston +9
Temporal variations in the dispersion measure (DM) of pulsars probe fluctuations in the free-electron density of the ionized interstellar medium (IISM). While DM variations have be…
JUG: JAX-based Unified pulsar timinG
Matthew T. Miles, Stephen R. Taylor, Matthew Bailes +14
We present JUG (JAX-based Unified pulsar timinG), a JAX-based, fully independent pulsar timing package emphasising speed and ease of use, designed to confidently handle the increas…
An updated constraint for the Gravitational Wave Background from the Gamma-ray Pulsar Timing Array
Serena Valtolina, Colin J. Clark, Rutger van Haasteren +5
Fermi LAT observations of gamma-ray pulsars can be used to build a pulsar timing array (PTA) experiment to search for gravitational wave (GW) signals at nanohertz frequencies. At t…
Dissecting the nanohertz gravitational wave sky: Frequency-correlated anisotropy induced by eccentric supermassive black hole binaries
Beatrice Eleonora Moreschi, Serena Valtolina, Alberto Sesana +5
Revealing the nature of the nanohertz gravitational wave (GW) signal recently reported by pulsar timing array (PTA) collaborations around the world is the next goal of low-frequenc…
The polarimetric response of the Nançay Radio Telescope and its impact on precision pulsar timing
Lucas Guillemot, Willem van Straten, Ismaël Cognard +3
In \citet{Guillemot2023} we presented a new method for calibrating pulsar observations conducted with the Nançay decimetric Radio Telescope (NRT), which significantly improved NRT…
Rapid Construction of Joint Pulsar Timing Array Datasets: The Lite Method
Bjorn Larsen, Chiara M. F. Mingarelli, Paul T. Baker +41
The International Pulsar Timing Array (IPTA)'s second data release (IPTA DR2) combines decades of observations of 65 millisecond pulsars from 7 radio telescopes. IPTA datasets shou…
Impact of the observation frequency coverage on the significance of a gravitational wave background detection in PTA data
Irene Ferranti, Mikel Falxa, Alberto Sesana +8
Pulsar Timing Array (PTA) collaborations gather high-precision timing measurements of pulsars with the aim of detecting gravitational wave (GW) signals. A major challenge lies in t…
Reading signatures of supermassive binary black holes in pulsar timing array observations
Boris Goncharov, Shubhit Sardana, A. Sesana +10
We find the inferred properties of the putative gravitational wave background in the second data release of the European Pulsar Timing Array to be in better agreement with theoreti…
The NANOGrav 15 yr Data Set: Chromatic Gaussian Process Noise Models for Six Pulsars
Bjorn Larsen, Chiara M. F. Mingarelli, Jeffrey S. Hazboun +61
Pulsar timing arrays (PTAs) are designed to detect low-frequency gravitational waves (GWs). GWs induce achromatic signals in PTA data, meaning that the timing delays do not depend…
A revisit of PSR J19093744 with 15-year high-precision timing
K. Liu, L. Guillemot, A. G. Istrate +10
We report on a high-precision timing analysis and an astrophysical study of the binary millisecond pulsar, PSR J19093744, motivated by the accumulation of data with well improve…
