Discovery of Two Consecutive Profile Change Events in the Millisecond Pulsar PSR J0437-4715
Rami F. Mandow, Andrew Zic, J. R. Dawson +19
The closest and brightest millisecond pulsar (MSP), PSR J0437-4715, is a high-priority pulsar for precision timing experiments, including the Parkes Pulsar Timing Array (PPTA) proj…
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…
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 (…
