The SKAO Pulsar Timing Array
Ryan M. Shannon, N. D. Ramesh Bhat, Aurelien Chalumeau +23
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21
We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…
Frequency- and phase-resolved polarimetry of millisecond pulsars and its application to timing
Małgorzata Curyło, Andrew Zic, Shuangqiang Wang +16
Pulsar timing is used for a variety of applications including tests of fundamental physics, probing the structure of neutron stars, and detecting nanohertz gravitational waves. Dev…
A glitch in the millisecond pulsar J09003144
Bhavnesh Bhat, Michael J. Keith, Ismaël Cognard +11
We report the detection of a glitch in the millisecond pulsar (MSP) PSR J09003144, which is included in the European, MeerKAT and Parkes pulsar timing array experiments. The dat…
Optimising the MeerKAT Pulsar Timing Array and towards precision pulsar timing with SKA-mid
Pratyasha Gitika, Ryan M. Shannon, Matthew Bailes +4
Pulsar timing arrays (PTAs) are Galactic-scale nanohertz-frequency gravitational wave (GW) detectors. Recently, several PTAs have found evidence for the presence of GWs in their da…
Ultra-Wideband Polarimetry of the April 2021 Profile Change Event in PSR J1713+0747
Rami F. Mandow, Andrew Zic, J. R. Dawson +15
The millisecond pulsar PSR J1713+0747 is a high-priority target for pulsar timing array experiments due to its long-term timing stability, and bright, narrow pulse profile. In Apri…
A carbon-rich atmosphere on a windy pulsar planet
Michael Zhang, Maya Beleznay, Timothy D. Brandt +17
A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR\,J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum…
A Multimessenger Search for the Supermassive Black Hole Binary in 3C 66B with the Parkes Pulsar Timing Array
Jacob Cardinal Tremblay, Boris Goncharov, Rutger van Haasteren +15
A subparsec supermassive black hole binary (SMBHB) at the center of the galaxy 3C 66B is a promising candidate for continuous gravitational-wave searches with pulsar timing arrays…
Searching for continuous gravitational waves in the Parkes Pulsar Timing Array Data Release 3
Shi-Yi Zhao, Zu-Cheng Chen, Jacob Cardinal Tremblay +19
We present results from an all-sky search for continuous gravitational waves from individual supermassive binary black holes using the third data release (DR3) of the Parkes Pulsar…
A simple optimisation for the MeerKAT Pulsar Timing Array
Hannah Middleton, Ryan M. Shannon, Matthew Bailes +9
The goal of the MeerKAT radio telescope's pulsar timing array programme (MPTA) is the detection of gravitational waves (GWs) of nanohertz frequencies. Evidence for such a signal wa…
