Nanohertz Gravitational-Wave Constraints on Supermassive Binary Black Holes at Cosmic Dawn
Yiqin Chen, Shi-Yi Zhao, Xingjiang Zhu +16
Standard continuous gravitational-wave searches with pulsar timing arrays (PTAs) neglect cosmological redshift, restricting their applicability to the local Universe. We introduce…
Interplanetary scintillation-informed heliospheric modelling for the MeerKAT Pulsar Timing Array 4.5 yr dataset
Saurav Mishra, Daniel J. Reardon, Andrew Zic +9
Heliospheric density variations impart delays on pulse times of arrivals from millisecond pulsars. Improper modelling of these variations may affect gravitational wave detection an…
Constraints on Ultralight Scalar and Dark Photon Dark Matter from PPTA-DR3 and EPTA-DR2
Xiao-Song Hu, Siyuan Chen, Kuo Liu +18
The cold dark matter model successfully describes the Universe on large scales, yet faces challenges at sub-galactic scales. Ultralight dark matter (ULDM), with particle masses aro…
Targeted search for eccentric supermassive binary black holes in OJ 287 and nearby galaxy clusters with PPTA DR3
Shi-Yi Zhao, Xingjiang Zhu, Jacob Cardinal Tremblay +19
We perform Bayesian targeted searches for continuous gravitational waves from eccentric supermassive binary black holes (SMBBHs) using the Parkes Pulsar Timing Array third data rel…
Searching for Anisotropy in the Gravitational Wave Background Using the Parkes Pulsar Timing Array
Yiqin Chen, Shi-Yi Zhao, Zhi-Zhang Peng +17
In recent years, several pulsar timing array collaborations have reported evidence for a nanohertz gravitational wave background (GWB). Such a background signal could be produced b…
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…
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 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…
Searching for gravitational-wave bursts from cosmic string cusps with the Parkes Pulsar Timing Array third data release
Yong Xia, Jingbo Wang, Sachiko Kuroyanagi +13
Pulsar timing arrays (PTAs) are designed to detect nanohertz-frequency gravitational waves (GWs). Since GWs are anticipated from cosmic strings, PTAs offer a viable approach to tes…
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…
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…
