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…
Towards DM-free search for Fast Radio Bursts with Machine Learning -- I. An implementation on multibeam data
Yao Chen, Rui Luo, Chen Wang +13
Searching for fleeting radio transients like fast radio bursts (FRBs) with wide-field radio telescopes has become a common challenge in data-intensive science. Conventional algorit…
Radio frequency interference identification using eigenvalue decomposition for multi-beam observations
Juntao Bai, Shi Dai, Na Wang +10
With the installation of next-generation phased array feed (PAF) receivers on radio telescopes, there is an urgent need to develop effective and computationally efficient radio fre…
The Parkes Observatory Pulsar Data Archive
Lawrence Toomey, George Hobbs, James Dempsey +3
Data from observations of pulsars made by Murriyang, the CSIRO Parkes 64-metre radio-telescope over the last three decades are more accessible than ever before, largely due to thei…
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…
Tiny-Scale Properties within the Interstellar Medium towards PSR J16444559: I. Observational Evidence of Turbulence-induced Tiny Scale Atomic Structures
Mengting Liu, Di Li, J. R. Dawson +21
We investigated HI absorption toward a single pulsar, PSR J16444559, and its variability over timescales from days to years, using Murriyang, CSIRO's Parkes Radio Telescope. Our…
First Search for Pulsed CH Maser Emission Stimulated by a Pulsar
Mengting Liu, Di Li, J. R. Dawson +6
We present the first search for pulsed CH maser emission potentially stimulated by PSR J16444559, conducted using the ultra-wide-bandwidth low-frequency receiver on Murriyang, C…
SDHDF: A new file format for spectral-domain radio astronomy data
L. J. Toomey, G. Hobbs, D. C. Price +17
Radio astronomy file formats are now required to store wide frequency bandwidths and multiple simultaneous receiver beams and must be able to account for versatile observing modes…
High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array
Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20
The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…
Applying saliency-map analysis in searches for pulsars and fast radio bursts
C. Zhang, C. Wang, G. Hobbs +9
To investigate the use of saliency-map analysis to aid in searches for transient signals, such as fast radio bursts and individual pulses from radio pulsars. We aim to demonstrate…
Radio observations of two intermittent pulsars: PSRs J1832+0029 and J1841-0500
S. Q. Wang, J. B. Wang, G. Hobbs +8
We present long-term observations of two intermittent pulsars, PSRs~J1832+0029 and J18410500 using the Parkes 64\,m radio telescope. The radio emission for these pulsars switche…
Observing Pulsars with a Phased Array Feed at the Parkes Telescope
X. Deng, A. P. Chippendale, G. Hobbs +9
During February 2016, CSIRO Astronomy and Space Science and the Max-Planck-Institute for Radio Astronomy installed, commissioned and carried out science observations with a phased…
Using the Parkes Pulsar Data Archive
J. Khoo, G. Hobbs, R. N. Manchester +2
The Parkes Pulsar Data Archive currently provides access to 165,755 data files obtained from observations carried out at the Parkes Observatory since the year 1991. Data files and…
The timing behaviour of radio pulsars
G. Hobbs
The purpose of this review paper is to summarise the pulsar timing method, to provide an overview of recent research into the spin-down of pulsars over decadal timescales and to hi…
