A coherent method for the detection and estimation of continuous gravitational wave signals using a pulsar timing array [PDF]

The Astrophysical Journal, 2014
The use of a high precision pulsar timing array is a promising approach to detecting gravitational waves in the very low frequency regime ($10^{-6} -10^{-9}$ Hz) that is complementary to the ground-based efforts (e.g., LIGO, Virgo) at high frequencies ($\

Exploring Pulsar Timing Precision: A Comparative Study of Polarization Calibration Methods for NANOGrav Data from the Green Bank Telescope [PDF]

The Astrophysical Journal
Pulsar timing array experiments have recently uncovered evidence for a nanohertz gravitational wave background by precisely timing an ensemble of millisecond pulsars.

Multi-method Timing of Transient Radio Pulsars with the GBT350 and GBNCC Surveys

The Astrophysical Journal
We present the timing solutions for three radio pulsars discovered with the Green Bank North Celestial Cap and 350 MHz Green Bank Telescope drift-scan surveys. These pulsars were initially discovered through their single-pulse emissions and are therefore

Applying clock comparison methods to pulsar timing observations [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Frequency metrology outperforms any other branch of metrology in accuracy (parts in 10−16) and small fluctuations (<10−17). In turn, among celestial bodies, the rotation speed of millisecond pulsars is by far the most stable (<10−18). Therefore, the precise measurement of the time of arrival (TOA) of pulsar signals

Pulsar timing methods for evaluating dispersion measure time series [PDF]

Astronomy & Astrophysics
Context. Radio pulsars can be used for many studies, including the investigation of the ionized interstellar medium and the solar wind via their dispersive effects. These phenomena affect the high-precision timing of pulsars and are among the main sources of noise in experiments searching for low-frequency gravitational waves in pulsar data. Aims.

Rapid construction of joint pulsar timing array data sets: the Lite method

Monthly Notices of the Royal Astronomical Society
ABSTRACT 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 data sets should be the most sensitive data sets to nanohertz gravitational waves (GWs), but take years to assemble, often excluding valuable recent data.
